my working out 1 + tan^2theta = sec^2theta
squareroot 1.16 = sec theta
sec theta= 1.07703
how do i find when its neg of pos?
thank you again
Hey this question above.
my working out
tan theta= 1/cot theta = cos theta/ sin theta
tan theta= cos ( -7/24) / sin(-7/24)
sin theta= -0.287549 or 0.29
the back of the book says
cos theta - 24/25, thats correct
but sin theta=-7/25 which equals -0.28
