Related to this Question What is 20 gradians in degrees? What is cos(15 degrees)? What is the cosine of 370 degrees? What is sine of 120 degrees? What is 3pi/4 in degrees? What is sin(-30 degrees)? What is the cos of 15 degrees?
The value of sin, cos, and tan of some angles are equal to the values of sin, cos, and tan of other angles. Let us take an example of cos(-30⁰). Since 30 degrees lie in the first quadrant we can say that cos(-30⁰) is equal to cos(30⁰) because all the angles in t...
