Question

Find the exact value of tan (arcsin (2/5)). For full credit, explain your reasoning. (PS can't see the chart/drawing attachments)

Answer 1

let u=arcsin(2/5)
so sin(u)=2/5
draw a right triangle using sin(u)=2/5
Then find the adjacent side to the angle u
Then use the fact that tan(u)=opp/adj to answer the question finally

Answer 2

okay thank you!
