Cos Sin Cot Degrees Radians

P.S.: For an angle larger than 45



select such angle from right-hand side and

obtain values in column corresponding to the function at bottom page. For the others

functions like cot 5 1/tan, csc 5 1/sin, sec 5 1/cos.

For an angle not found in the previous table, you can use the following rules:

sin(2θ) 52sin θ

cos(2θ) 5 cos θ

tan(2 θ) 52tan θ
