Question

Given sinx=3/5 and x is in quadrant 2 what is the value of tan x/2

Answer 1

so,
sinx = 3/5
sin^-1 (3/5) = x
x= 36.86 degrees.

Answer 2

now remember tan is negative.
-tan (x/2) = -tan (36.86/2) = -0.3333
= -1/3

Answer 3

@study100 Thanks for explaining the quadrants to me and all of this this was really helpful

Answer 5

Hold on @study100 I hsd a question like this earlier it was given sinx=-4/5 and x is in the quadant 3 what is the value of tanx/2 and it told me the answer was -2

Answer 6

@study100 i think this question wants somthing other than a fraction
