Basic trig identities are formulas for angle sums, differences, products, and quotients; and they let you find exact values for trig expressions.

Convert from 1 cos(t) 1 cos (t) to sec(t) sec (t). Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used.

For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. When we divide Sine by Cosine we get: So we can say: That is our first Trigonometric Identity.

Identities expressing trig functions in terms of their supplements. sin ( t) = sin t. cos ( t) = cos t. tan ( t) = tan t. Difference formulas for sine and cosine. Sum, difference, and double angle formulas for tangent. Half-angle formulas. These are just here for perversity.

The cotangent formula for an angle θ is: cot θ = (Adjacent side) / (Opposite side). Let us take a look at the right-angled triangle ABC that is right-angled at B. Then AB is the side that is adjacent to A and BC is the side that is opposite to A. Then cotangent of A (which is written as cot A) is,
