Answer 4

You've typed: "if cos x = 3/5 what is the positive value of sin 1/2 x? (don't understand this question completely please give answer and small explanation)."

First: I need clarification: Do you mean sin (1/2)x or sin (x/2)? ("the sine of half of x"?)

Second: Can you draw a triangle in the first quadrant so that the angle x has adjacent side 3 and hypotenuse 5 (since cos x = 3/5)?

Answer 5

@mathmale I mean sin sin (1/2)x and the second thing is no

Answer 6

Are you positive that your question includes "sin" twice?
