Answer:
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). ... And the 3 new functions are secant theta, cosecant theta and cotangent theta. Secant theta is defined as 1 over x. Cosecant theta is 1 over y and cotangent is x over y.
