Best ResponseYou've already chosen the best response.0you are looking for \[\int^2_0 \frac{3}{\sqrt{16x^2}}dx \]?

Best ResponseYou've already chosen the best response.0I know that it has to do with the sine identity, but I keep getting the wrong answer using that. My answer is never an angle that is correct

Best ResponseYou've already chosen the best response.0[S] 3 dt > 3t ... what does t revert back to tho? x = 4sin(t) x/4 = sin(t) sin^1(x/4) = t if i did it right :)

Best ResponseYou've already chosen the best response.0I pulled out the three and had (1/4)arcsin(x/4) evaluated from 0 to 2

Best ResponseYou've already chosen the best response.0evaluate at upper limit, get \[sin^{1}(\frac{2}{4})=sin^{1}(\frac{1}{2})=\frac{\pi}{6}\] plug in 0 get 0 so answer is \[\frac{\pi}{6}\]

Best ResponseYou've already chosen the best response.0So when I get a decimal, how can I revert it make to degrees/radians so that the computer will except it?

Best ResponseYou've already chosen the best response.0the area is the area. As a function this is a function of numbers, not degrees or radians. It corresponds to the radian measure of the angle, not the degree measure. Always work in 'radians' if you are thinking of angles. But they are just numbers.
