Sin cos tan قوانين. Plot of the six trigonometric functions the unit circle and a line for the angle θ 0 7 radians. Cot a cot b sin a b sin a sin b. 3a 4a and so on. Sin θ tan θ and 1 are the heights to the line starting from the x axis while cos θ 1 and cot θ are lengths along the x axis starting from the origin.

There s a very cool second proof of these formulas using sawyer s marvelous idea also there s an easy way to find functions of higher multiples. To get the formula for tan 2a you can either start with equation 50 and put b a to get tan a a or use equation 59 for sin 2a cos 2a and divide top and bottom by cos a. Tangent of a double angle. The angle is 60 degrees.

The points labelled 1 sec θ csc θ represent the length of the line segment from the origin to that point. Displaystyle tan a tan b frac sin a b cos a cdot cos b tana tanb cosa cosbsin a b.
