<\/span><\/p>\n The three ratios sin, cos, and tan have their individual formulas. Suppose ABC is a right-angled triangle, right-angled at B, as shown in the figure below:<\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n The three sides in the right-angled triangle are given below:<\/span><\/p>\n AB = Adjacent side to angle \u03b8<\/span><\/p>\n BC = Opposite side to angle \u03b8<\/span><\/p>\n CA = Hypotenuse to angle \u03b8<\/span><\/p>\n Now as per sin, cos and tan formulas, we have:<\/span><\/p>\n sin \u03b8 = Opposite side \/ Hypotenuse = BC \/ CA<\/span><\/p>\n cos \u03b8 = Adjacent side \/ Hypotenuse = AB \/ CA<\/span><\/p>\n tan \u03b8 = Opposite side \/ Adjacent side = CB \/ AB<\/span><\/p>\n <\/span><\/p>\n Let us see the table where the values of sin, cos, and tan are provided for the standard angles 0\u00b0, 30\u00b0 (\u03c0\/6), 45\u00b0 (\u03c0\/4), 60\u00b0 (\u03c0\/3) and 90\u00b0 (\u03c0\/2).<\/span><\/p>\n <\/span><\/p>\n For finding sin, cos, tan values, follow the below steps:<\/span><\/span><\/p>\n \n \n \n <\/span><\/p>\n \n <\/span><\/p>\n \n <\/span><\/p>\n sin (180\u00b0 \u2212 x) = sin x<\/span><\/p>\n sin (180\u00b0 + x) = – (sin x)<\/span><\/p>\n sin (360\u00b0 \u2212 x) = – (sin x)<\/span><\/span><\/p>\n This means,<\/span><\/p>\n sin 180\u00b0 = sin (180\u00b0 \u2212 0\u00b0) = sin 0\u00b0 = 0<\/span><\/p>\n sin 270\u00b0 = sin (180\u00b0 +90\u00b0) = – (sin 90\u00b0) = -1<\/span><\/p>\n Sin 360\u00b0 = sin (360\u00b0 \u2212 0\u00b0) = – (sin 0\u00b0) = 0<\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n \n <\/span><\/p>\n For example, the value of tan 30\u00b0 = (sin 30\u00b0\/cos 30\u00b0) = (\u00bd) \/(\u221a3\/2) = (1\/\u221a3). Similarly, we can generate the other values.\u00a0<\/span><\/p>\n \n <\/span><\/p>\n The value of trigonometric functions for angles ranging from 0\u00ba to 360\u00ba is given in the following trigonometry table.\u00a0<\/span><\/p>\n \n <\/b><\/p>\n We know that, sin 270\u00b0 = sin (180\u00b0 + 90\u00b0)\u00a0<\/span><\/p>\n Also, sin (180\u00b0 + x) = – (sin x)<\/span><\/p>\n Therefore, sin (180\u00b0 + 90\u00b0) = – sin 90\u00b0 = – 1<\/span><\/p>\n Hence, sin 270\u00b0 = – 1<\/span><\/p>\n <\/p>\n The trigonometry table helps us to find these values quickly. We have:<\/span><\/p>\n (a) sin(\u03c0\/4) = sin 45\u00ba = (1\/\u221a2)<\/span><\/p>\n (b) cos(\u03c0\/3) = cos 60\u00ba = (1\/2)<\/span><\/p>\n (c) tan (\u03c0\/2) = tan 90\u00ba = \u221e<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ module_id=”stickysideR” admin_label=”Column R” _builder_version=”4.10.4″ _module_preset=”default” background_color=”#fdefe0″ custom_padding=”25px|25px|25px|25px|true|true” sticky_position=”top” sticky_offset_top=”-280px” sticky_limit_top=”row” sticky_limit_bottom=”row” sticky_position_tablet=”none” sticky_position_phone=”none” sticky_position_last_edited=”on|desktop” sticky_limit_bottom_tablet=”” sticky_limit_bottom_phone=”” sticky_limit_bottom_last_edited=”on|phone” border_radii=”on|15px|15px|15px|15px” box_shadow_style=”preset3″ global_colors_info=”{}”][et_pb_image src=”https:\/\/eistudymaterial.s3.amazonaws.com\/1080×1080.png” alt=”Free Trial banner” title_text=”Mindspark Free Trial Banner” url=”https:\/\/mindspark.in\/free-trial” align=”center” module_class=”adsimg” _builder_version=”4.11.1″ _module_preset=”default” custom_padding=”||||false|false” border_radii=”on|10px|10px|10px|10px” global_colors_info=”{}” transform_styles__hover_enabled=”on|hover” transform_scale__hover_enabled=”on|hover” transform_translate__hover_enabled=”on|desktop” transform_rotate__hover_enabled=”on|desktop” transform_skew__hover_enabled=”on|desktop” transform_origin__hover_enabled=”on|desktop” transform_scale__hover=”102%|102%”][\/et_pb_image][et_pb_text admin_label=”Explore Other Topics [\/et_pb_text][et_pb_text _builder_version=”4.10.7″ _module_preset=”default” text_line_height=”2.2em” link_font_size=”16px” custom_margin=”||0px||false|false” custom_padding=”10px|15px|10px|28px|true|false” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text admin_label=”Related Concepts [\/et_pb_text][et_pb_text _builder_version=”4.13.1″ _module_preset=”default” text_line_height=”2.2em” link_font_size=”16px” custom_margin=”||0px||false|false” custom_padding=”10px|15px|10px|28px|true|false” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”Row for space” _builder_version=”4.10.6″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.9.11″ _module_preset=”default” global_colors_info=”{}”][et_pb_divider show_divider=”off” _builder_version=”4.10.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_divider][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”banner and faq Section” module_class=”mainsec2″ _builder_version=”4.10.4″ _module_preset=”default” custom_padding=”40px||0px||false|false” global_colors_info=”{}”][et_pb_row use_custom_gutter=”on” gutter_width=”1″ make_equal=”on” disabled_on=”on|on|off” admin_label=”banner Row” _builder_version=”4.10.4″ _module_preset=”default” background_color=”#fff7d6″ width=”100%” max_width=”1310px” height=”134px” custom_margin=”||50px||false|false” custom_padding=”12px||12px||true|false” border_radii=”on|11px|11px|11px|11px” locked=”off” collapsed=”off” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.9.10″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/stgwebsite.mindspark.in\/wordpress\/wp-content\/uploads\/2021\/08\/calloutImage.png” title_text=”calloutImage” show_bottom_space=”off” admin_label=”Image” module_class=”img1″ _builder_version=”4.10.8″ _module_preset=”default” width=”25px” height=”60px” custom_padding=”2px||2px||true|false” global_colors_info=”{}”][\/et_pb_image][et_pb_text module_class=”ftstyle” _builder_version=”4.9.10″ _module_preset=”default” text_orientation=”center” global_colors_info=”{}”]<\/p>\nSin Cos Tan Formula<\/b><\/h2>\n
