Answer
$$\cos \psi= 0.3, \quad \sin\psi= 0.95$$
$$\cot\psi=0.32, \quad \csc\psi= 1.05.$$
Work Step by Step
By making use of the Pythagorean theorem, we have $$\cos \psi=\frac{0.3}{1}=0.3, \quad \sin\psi=\frac{\sqrt{1-0.3^2}}{1}=0.95$$
$$\cot\psi=\frac{\cos \psi}{\sin\psi}=\frac{0.3}{0.95}=0.32, \quad \csc\psi=\frac{1}{\sin\psi}=\frac{1}{0.95}=1.05.$$
