The derivative of arcsin is given by arcsin0(x) = 1 ? 1 ? x2 Proof: For x ? [?11] holds arcsin0(x) = 1 sin0 arcsin(x) = 1 cos arcsin(x) For x ? [?11] we get arcsin(x) = y ? h? 2 ? 2 i and the cosine is positive in that interval then cos(y) = + q 1 ? sin2(y) hence arcsin0(x) = 1 q 1 ? sin2 arcsin(x) ? arcsin 0(x) = 1
Section 5 5 Inverse Trigonometric Functions and Their Graphs DEFINITION: The inverse sine function denoted by sin 1 x (or arcsinx) is de ned to be the inverse of the restricted sine function
Thus we see that the cosine of the angle (and hence the answer to the problem) is 1/ ? 10 1 3 10 Derivative of the Arcsine and the Arctangent Arcsine: Now that we have de?ned inverse functions for some of the trigonometric functions we will ?nd their derivatives
The derivative of arccos x is the negative of the derivative of arcsin x. That will be true for the inverse of each pair of cofunctions. The derivative of arccot x will be the negative of the derivative of arctan x. The derivative of arccsc x will be the negative of the derivative of arcsec x. For, beginning with arccos x:
The derivative of the arcsine with respect to its argument is equal to 1 over the square root of 1 minus the square of the argument. Here is the proof:
y = arcsin x implies sin y = x. And similarly for each of the inverse trigonometric functions. Problem 1. If y = arcsin x, show: To see the answer, pass your mouse over the colored area. To cover the answer again, click "Refresh" ("Reload"). Do the problem yourself first! x. according to line 1).
In the same way that we can encapsulate the chain rule in the derivative of as , we can write formulas for the derivative of the inverse trigonometric functions that encapsulate the chain rule. Note that represents a function of in these formulas, and represents the derivative of with respect to .
