To find the derivative of xsec^2(x) with respect to x, we can use the chain rule. First, we need to express xsec^2(x) in terms of its reciprocal function, csc(x).
xsec^2(x) = 1/(csc(x))^2
Using the reciprocal function identities, csc(x) = 1/sin(x) and sec(x) = 1/cos(x), we can then express xsec^2(x) as:
xsec^2(x) = (cos(x))^2/(sin(x))^2
Now we can take the derivative of xsec^2(x) using the chain rule:
d/dx(xsec^2(x)) = 2cos(x)(-sin(x))(cos(x))/(sin(x))^2 + (cos(x))^2(-1/sin(x))*(cos(x))
Simplifying the equation, we get:
d/dx(xsec^2(x)) = tan(x)*sec^2(x)
So the derivative of xsec^2(x) with respect to x is tan(x)*sec^2(x).
