In quadrants 1 and 2 sin will have the same value. Is the inverse of sin the same as the cosecant, arccos sqrt2/2. Cancel Send Feedback.

.

The arccos function allows the calculation of the arc cosine of a number. The arccos function is the inverse functions of the cosine function. Arccosine function The arccosine function is the inverse function of the cosine function , it calculates the arc cosine of a number online. The number on which you wish to apply the fonction arccosine function must belong to the range [-1,1]. To calculate the arccosine of a number, just enter the number and apply the arccos function. Thus, for calculating the arccosine of the number following 0. To differentiate function arccosine online, it is possible to use the derivative calculator which allows the calculation of the derivative of the arccosine function. Antiderivative calculator allows to calculate an antiderivative of arccosine function. The limit calculator allows the calculation of limits of the arccosine function.

The range you mentioned sweeps over all the possible values from -1 to 1 without any repeats. Suggested Textbook. I have no idea how to actually figure out arcsin, arccos or arctan after watching these three videos. So let's restrict its range. Login Sign up. And I want to figure out the inverse sign. Now you might have that memorized. That is, if you multiplied sin and csc, the product would be 1. So we restrict the range so we get one answer. I get the exact same value. Now what angle gives me that?

.

Or we could say the inverse sign of minus square root of 3 over 2 is equal to minus pi over 3 radians. Note: Only the first five people you tag will receive an email notification; the other tagged names will appear as links to their profiles. Cosecant is the multiplicative inverse of sin. Comment Button navigates to signup page. That's So in order for this to be a valid function-- In order for the inverse sine function to be valid, I have to restrict its range. This is all review. Let's think about it a little bit. Find the exact value of the trigonometric function. The possible values.
