Solve 4 sin (5t)-1 = 1 for all possible values. Draw picture to support your answer. Can someone help me for this question? I don’t know how to solve this problem. ASAP

The answer to your question is   t₁ = 6 and t₂ = 30

Step-by-step explanation:

                           4sin(5t) -1 = 1

Solve as a common equation

                           4sin(5t) = 1 + 1

                           4sin(5t) = 2

                             sin(5t) = 2/4

                             sin(5t) = 1/2

sin of 1/2 = 30° and 150°          sin 30 = 1/2   and sin 150 = 1/2

Then

               5t = 30°              and     5t = 150°

                 t₁ = 30/5                         t = 150/5

                t₁ = 6                               t₂ = 30

a. is correct
