Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical ...
Rewrite 67.5 67.5 as an angle where the values of the six trigonometric functions are known divided by 2 2. tan(135 2) tan ( 135 2) Apply the tangent half - angle identity. ±√ 1−cos(135) 1+cos(135) ± 1 - cos ( 135) 1 + cos ( 135) Change the ± ± to + + because tangent is positive in the first quadrant.

4 de mar. de 2024 · Yes, you're right! The antilogarithm is simply the exponentiation! To calculate an antilog of any number y y, you need to raise the logarithm base b b (usually 10, sometimes e e) to the power of y y: \small x = \log_b^ {-1} (y) = b^y x = logb−1(y) = by. Since log and antilog are inverse functions, then this means that:
