Question

If possible, find a solution to sin(theta) = 3/4. If no solution exists, enter NONE.

Answer 1

try drawing the graph of sine first, just to visualize this

Answer 2

so, first, do you think a solution exists?

Answer 3

what are the max and min values of sine?

Answer 4

1 and -1

Answer 5

all right, cool, and sine is a continuous function

Answer 6

so it can be any values between and including [-1,1]

Answer 7

okay I get it now thanks

Answer 8

ok, yeah, this wants the angle, probably in radians, such that the sine of that angle is 3/4
