What is the exact value of cosθ, secθ, cotθ?

Question

(-7, 3) is a point on the terminal side of θ.

Answer 1

x=-7 = adjacent

y = 3 = opposite

hypotenuse is sqrt( 9 + 49) = sqrt(58)

sine is 3/sqrt(58) = 3 * srt(58)/58

cosine is -7/sqrt(58) = -7*sqrt(58)/58

tangent = -3/7

cosecant is sqrt(58)/3

secant is -sqrt(58)/7

cotangent = -7/3
