What is COS 30 in radians?

To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° or 2π radians. The exact value of cos(30) is √32 .

How do you find cos 45 degrees?

Cos 45° Value The exact value of cos 45 degrees is 1/√2 (in surd form), which is also equal to sin 45 degrees. It is an irrational number, equal to 0. in decimal form. The approximate value of cos 45 is equal to 0.7071.

How do you turn sin into cos?

All triangles have 3 angles that add to 180 degrees. Therefore, if one angle is 90 degrees we can figure out Sin Theta = Cos (90 – Theta) and Cos Theta = Sin (90 – Theta).
