sec2x

The formula for differentiation of tan x is, d/dx (tan x) = sec2x (or) (tan x)’ = sec2x.

## What does Cos 3x mean?

Cos3x is a triple angle identity in trigonometry. It is a specific case of compound angles identity of the cosine function. Cos3x gives the value of cosine trigonometric function for triple angle.

**What is the formula of tangent?**

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .

### What is the double angle identity for tangent?

tangent double-angle identity can be accomplished by applying the same methods, instead use the sum identity for tangent, first. Therefore, 1+ sin 2x = 1 + sin 2x, is verifiable. The alternative form of double-angle identities are the half-angle identities.

### What is the derivative of tangent squared?

2 sec2x

Answer: The derivative of y = tan2x is dy/dx = 2 sec2x tan x.

**What is the derivative of inverse tangent?**

#### How do you convert COSX to cos3x?

This can be simplified further as cos^3x = (1/4) cos3x + (3/4) cosx. Also, we know that the reciprocal identity of cosine function is cosx = 1/secx.

#### What is the derivative of cos3x?

The formula for the derivative of cos3x is equal to -3 sin3x. The differentiation of cos^3x is equal to -3 cos2x sinx. We can evaluate the differentiation of cos3x and cos^3x using the first principle of derivatives and chain rule method.
