Find the Exact Value tan(arcsin(3/5))
Problem
Solution
Identify the inner function as an angle
θ whereθ=arcsin(3/5) Rewrite the expression using the definition of the inverse sine function, which implies
sin(θ)=3/5 forθ in the interval[−π/2,π/2] Relate the sine value to a right triangle where the opposite side is
3 and the hypotenuse is5 Calculate the adjacent side
b using the Pythagorean theorema2+b2=c2
Determine the value of
tan(θ) using the ratio of the opposite side to the adjacent side.
