We can use the double angle cosine formula here: cos (2θ) = 1 - 2 (sinθ) 2. Since cosθ is 24/25, we can infer the length of the third side since 24,25 is part of a pythagorean triple of 7,24,25. So sinθ = -7/25 (negative because θ is in the fourth quadrant). So cos (2θ) = 1 - 2 (-7/25) 2 = 527/625. korean visa without itrWebMar 30, 2024 · sintheta=("-"7)/25 costheta=24/25 tantheta=("-"7)/24 cottheta=("-"24)/7 sectheta=1/24 csctheta=("-"1)/7 Let the point P(x,y) be on a circle of radius r centered at the origin and P is on the terminal ray of theta.
