If θ is an angle in standard position and its
terminal side passes through the point (−3,2), find
the exact value of cscθ .
I know the answer...but i want to know how you get the answer...
The answer is
radical 13/2

  • math(advanced algebra&trigonometry) -

    construct a triangle by drawing a perpendicular from the point (-3,2) to the x-axis.
    by Pythagoras the hypotenuse is √(9+4) = √13

    by definition cscθ = r/y = √13/2
