(1 point) Suppose following. Enter exact answers given as fractions, not decimal approximations. help (fractions) 1. COS 2. Sin 3, tan(0) (Not drawn to scale)

Solution

phi=theta

It means that its an isosceles right triangle,with phi=theta=45 degree

And x=y

cos theta=adjacent /hypotenuse = x/z

sin theta=opposite/hypotenuse=y/z

tan theta= opposite/adjacent= y/x=1   (since x=y)
