Wronskian of e^x*cos(√x) and e^x*sin(√x)

[Math10]

Homework Statement

Find the Wronskian of {e^(x)*cos(sqrt(x)), e^(x)*sin(sqrt(x))}.

Homework Equations

W(f, g)=fg'-gf'

The Attempt at a Solution

W(f, g)=(e^(x)*cos(sqrt(x)))(e^(x)*cos(sqrt(x))*1/(2x^1/2))-(e^(x)*sin(sqrt(x)))(-e^(x)*sin(sqrt(x))*1/(2x^1/2)+e^(x)*cos(sqrt(x)))
After simplifying this, I got (e^(2x)(1-2*sqrt(x)*sin(sqrt(x))*cos(sqrt(x)))/(2x^(1/2)). But the correct answer is e^(2x)/(2x^1/2).

It would help a lot if you edited your post to use latex for your math expressions.

I agree. With almost 250 posts, it is time to learn latex.

Never mind, I found the mistake in my problem.
