is cos 1 over sec The notation cos 1 x means the same thing as arccos x If you wanted to talk about sec x which is 1 cos x you would write cos x 1
Trigonometric Identities Practice Questions Solve the below practice questions based on the trigonometry identities that will help in understanding and applying the formulas in an effective way Express the ratios cos A tan A and sec A in These are also known as the angle addition and subtraction theorems or formulae The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that and They can also be derived by using a slightly modified version of the figure for the angle sum identities b
