Most useful: https://en.wikipedia.org/wiki/Pythagorean_trigonometric_identity#Related_identities Most general: https://en.wikipedia.org/wiki/List_of_trigonometric_identities Just treat cos(x) as a single object, then you can just shuffle things around to get the answer once you find the right identity.

Zayne Messages 981 Reaction score 1,928 Points 610 May 15, 2020 #14 I haven't done this in years but here's what I got. General equation: sin^2(x) + cos^2(x) = 1 ------- 5. if sin(x) = 0.8 (0.8)^2 + cos^2(x) = 1 cos^2(x) = 1 - 0.64 = 0.36 cos(x) = 0.6 6. if cos(x) = 0.6 sin^2(x) + (0.6)^2 = 1 sin^2(x) = 1 - 0.36 = 0.64 sin(x) = 0.8 7. if cos(x) = 0.8 sin^2(x) + (0.8)^2 = 1 sin^2(x) = 1 - 0.64 = 0.36 sin(x) = 0.6 tan(x) = sin(x)/cos(x) tan(x) = 0.6/0.8 tan(x) = 0.75 8. if sin(x) = 0.5 (0.5)^2 + cos^2(x) = 1 cos^2(x) = 1 - 0.25 = 0.75 cos(x) = 0.86602540378 cot(x) = 1/tan(x) = cos(x)/sin(x) cot(x) = 0.86602540378/0.5 cot(x) = 1.73205080756 D. tan^-1(1) = 45 deg tan(x) = sin(x)/cos(x) for tan(x) == 1, sin(x) must be equal to cos(x) I can't explain this properly ask Tiny lol. E. if cot(x) = tan(x) cot(x) = 1/tan(x) tan(x) = 1/tan(x) tan(x) * tan(x) = 1 tan^2(x) = 1 tan(x) = sqrt(1) = 1 tan-1(1) = 45 deg same as D.
