    imaginary zeros, trigonometric functions, polor equations
    simply this expression csc (theta)- cos (theta) cot (theta)


    find two real and imaginary zeros for this function: f(x)= x^4+x^3-2x^2+4x-24



    convert these polar equations to rectangular form:

    r=3csc (theta) r=6sin (theta)






    simplify this expression: cos[sin^-1(square root of 3/2)]
