Understand the function: Understand the function and what is being asked.We need to find the derivative of y with respect to x, where y=csc−1(2x4+6). This is an application of implicit differentiation and the chain rule.
Differentiate both sides: Differentiate both sides of the equation with respect to x. Starting with y=csc−1(2x4+6), we differentiate both sides with respect to x. The left side becomes dxdy, and the right side requires the use of the chain rule.
Apply inverse cosecant derivative: Apply the derivative of the inverse cosecant function.The derivative of csc−1(u) with respect to u is −(∣u∣u2−1)1, where u is a function of x. In this case, u=2x4+6.
Apply the chain rule: Apply the chain rule.Now we need to multiply the derivative of csc−1(u) by the derivative of u with respect to x, which is dxd(2x4+6)=8x3.
Combine to find dy/dx: Combine the results to find dy/dx.So, dy/dx=−∣2x4+6∣(2x4+6)2−11⋅8x3.
Simplify the expression: Simplify the expression.Since 2x4+6 is always positive for all real x, we can remove the absolute value. Also, we can expand the square and subtract 1 inside the square root.dxdy=(2x4+6)(2x4+6)2−1−8x3.
Further simplify if possible: Further simplify the expression if possible.The expression is already in its simplest form, so no further simplification is needed.
