Given function: We are given the function y=sin−1(9x+61). To find the derivative of y with respect to x, we will use the chain rule and the derivative of the inverse sine function.
Derivative of inverse sine function: The derivative of the inverse sine function, sin−1(u), with respect to u is 1−u21. Here, u=9x+61. We will apply the chain rule to take the derivative of y with respect to x.
Derivative of u with respect to x: First, we find the derivative of u with respect to x, where u=9x+61. The derivative of u1 with respect to u is −u21, and the derivative of 9x+6 with respect to x is x0. So, the derivative of u with respect to x is x3.
Chain rule application: Now, we apply the chain rule: (dxdy)=(dudy)⋅(dxdu). We already have (dudy)=1−u21 and (dxdu)=(9x+6)2−9.
Substitute u back: Substitute u back into the expression for dudy to get dudy=1−(9x+61)21.
Multiply to find derivative: Now, multiply (dy)/(du) by (du)/(dx) to get the derivative of y with respect to x: (dy)/(dx)=(1/1−(1/(9x+6))2)∗(−9/(9x+6)2).
Simplify expression: Simplify the expression for dxdy by combining the terms: dxdy=(9x+6)2−9×1−(9x+61)21.
Further simplify expression: Further simplify the expression by combining the denominators: (dxdy)=(9x+6)21−(9x+61)2−9.
