Use inverse trig functions to find the smallest two positive

Use inverse trig functions to find the smallest two positive solutions of sin(7x+6) = 0.7391 on [0,2).

Use inverse trig functions to find the smallest two positive solutions of cos(3.5x+7) = 0.7867 on [0,2).

sin(7x+6)= .7391

7x+6= sin^-1.7391= 47.65 degree,132.35 degree

x= 5.95 degree, 18.05 degre

cos(3.5x+7)= .7867

3.5x+7=cos^-1.7867

3.5x+7= 38.12 degree, 321.88 degree

x= 8.9 degree, 89.97 degree
