What is the integral of sine function?
The integral of sin x is -cos x. Mathematically, this is written as ∫ sin x dx = -cos x + C, were, C is the integration constant.
What is the integral of cosine?
The integral of cos x dx is sin x. Mathematically, this is written as ∫ cos x dx = sin x + C, where, C is the integration constant. Here, ‘∫’ is a symbol of integration and it is known as the “integral”
How many trig functions are there?
six functions
There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What are trig functions used for?
Trigonometric functions are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. If we are given one angle in a right triangle and we know that the measure of the hypotenuse is 2, what are the measures of the two other legs?
How to integrate trig functions?
– ∫ sin x dx = -cos x + C – ∫ cos x dx = sin x + C – ∫ sec 2 x dx = tan x + C – ∫ cosec 2 x dx = -cot x + C – ∫ sec x tan x dx = sec x + C – ∫ cosec x cot x dx = -cosec x + C – ∫ tan x dx = ln | sec x | + C – ∫ cot x dx = ln | sin x | + C – ∫ sec x dx = ln | sec x + tan x | + C – ∫ cosec x dx = ln | cosec x – cot x | + C
What are the six trigonometry functions?
Secant (sec)
When to use trig substitution?
It is a good idea to make sure the integral cannot be evaluated easily in another way.
