What is SEC integration?
The integral of sec x is ln|sec x + tan x| + C. It denoted by ∫ sec x dx. This is also known as the antiderivative of sec x. We have multiple formulas for this. But the more popular formula is, ∫ sec x dx = ln |sec x + tan x| + C.
What is the integral of the sine function?
The integral of sinx is −cosx+C and the integral of cosx is sinx+C. …
What are the common integrals?

What are derivatives and integrals?
The derivative of a function can be geometrically interpreted as the slope of the curve of the mathematical function f(x) plotted as a function of x. The integral gives you a mathematical way of drawing an infinite number of blocks and getting a precise analytical expression for the area.
What is integral and differential calculus?
While differential calculus focuses on rates of change, such as slopes of tangent lines and velocities, integral calculus deals with total size or value, such as lengths, areas, and volumes. …
How do you find the differentiation of trigonometric functions?
Differentiation of Trigonometric Functions. It is possible to find the derivative of trigonometric functions. Here is a list of the derivatives that you need to know: d (sin x) = cos x. dx. d (cos x) = –sin x. dx. d (sec x) = sec x tan x. dx.
How do you integrate trigonometric functions?
Integration of Trigonometric functions involves basic simplification techniques. These techniques use different trigonometric identities which can be written in an alternative form that are more amenable to integration.
How do you find the derivative of an inverse trigonometric function?
The following derivatives are found by setting a variable y equal to the inverse trigonometric function that we wish to take the derivative of. Using implicit differentiation and then solving for dy / dx, the derivative of the inverse function is found in terms of y.
What is constant of integration in trigonometry?
C is called constant of integration or arbitrary constant. x is the variable of integration. To understand this concept let us solve some examples. Example- Integrate 2cos2x with respect to x. Solution- To integrate the given trigonometric functions we will use the trigonometric identity –
