Hi! My problem is find all solutions for sin (theta) - 1 = 0

OpenStudy (anonymous):

adding 1 to both sides you have sin(theta)=1

OpenStudy (anonymous):

Take sin^-1 (1) on a calculator, or use your good trig knowledge to do it by head

you will need to know what value sine(x)=1 for, its very important so just memorize it (that goes for cosine(x) too)
