### Inverse Trigonometric functions

The inverse trigonometric functions are also called arcus functions or anti trigonometric functions. ... Specifically, they are the inverse functions of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios.
What is the inverse of sin?
The symbol for inverse sine is sin-1, or sometimes arcsin

What are principal values in trigonometry?
Principal values for sin, cos and tan. has one solution in this interval called theprincipal value of θ. It is in the first or fourth quadrant. Any equation cos θ = C for the domain [0, π], has one solution in this interval called the principal value of θ.

What quadrants is Arccos restricted to?
The range, then, of y = arccos x will be from 0 to π. An angle whose cosine is positive will be a 1st quadrant angle; an angle whose cosine is negative will fall in the 2nd. It will be the supplement of the 1st quadrant angle.

What quadrants are inverse trig functions in?
The domain of the inverse tangent function is (−∞,∞) and the range is (−π2,π2) . The inverse of the tangent function will yield values in the 1st and 4th quadrants. The same process is used to find the inverse functions for the remainingtrigonometric functions--cotangent, secant and cosecant.

What is the inverse of 1 2?
Answer and Explanation: The multiplicative inverse of 1/2 is 2. To determine themultiplicative inverse of a number, we use the following rule: The multiplicative inverse...

What is sin to the negative 1?
The inverse sin of 1, ie sin-1 (1) is a very special value for the inverse sine function. Remember that sin-1(x) will give you the angle whose sine is x . Therefore, sin-1 (1) = the angle whose sine is 1

What is the inverse of tan?
Inverse tangent is also called arctangent and is labeled \begin{align*}\tan^{-1}\end{align*} or arctan. The “-1” indicates inverse. Inverse Sine: If you know the opposite side of an angle and the hypotenuse in a right triangle, you can use inverse sine to find the measure of the angle
