Hi, I have another question that I am having trouble with:
Find the value of a such that:
[tex]\int_{0 }^{a } cos^2 (x) dx[/tex]
[tex]\frac{x}{2} + \frac{(sin(2x)}{4} [/tex]
[tex]\frac{a}{2} + \frac{sin(2a)}{4} - 0 - 0 = 0.740[/tex]
[tex]\frac{a}{2} + \frac{sin(2a)}{4} = 0.740[/tex]
[tex] 2a + sin(2a) = 2.96[/tex]
I am stuck after this...How would I solve the trig equation?
Maybe...[tex] m + sin(m) = 2.96[/tex]
where m = 2a
But I don't think that will get me anywhere :-/
Thanks for your help!
Homework Statement
Find the value of a such that:
[tex]\int_{0 }^{a } cos^2 (x) dx[/tex]
The Attempt at a Solution
[tex]\int_{0}^{a}\frac{1}{2} (1+cos (2x))[/tex][tex]\frac{x}{2} + \frac{(sin(2x)}{4} [/tex]
[tex]\frac{a}{2} + \frac{sin(2a)}{4} - 0 - 0 = 0.740[/tex]
[tex]\frac{a}{2} + \frac{sin(2a)}{4} = 0.740[/tex]
[tex] 2a + sin(2a) = 2.96[/tex]
