![]() ![]() That your calculator, or if you're doing this, And then you want theīounds of integration, and you should assume We'd put in a theta here then we would want to putĪ theta there as well. And then the next one, you specify, "Well what's the variable you're taking "the integral with respect to?" In this case it's x, if Of sine of theta squared, we're once again assuming So I tend to use just the "x" button, because there is an "x" button, but we'll just assume that Here, as long as I'm consistent with what I'm The parentheses, sine, and I could use any variable So let's use that function,Īnd then the first thing, you want to say "well, what are you taking "the definite integral of?" And we're taking theĭefinite integral of. Sin squared theta d theta, so how do I do that? Well I can go to second,Ĭalculus, then I do the F N INT, that's definite integral. Times the definite integral from zero to pi over four You're dealing with Cartesian coordinates, rectangular coordinates, or for polar coordinates,Ĭause it's really just about evaluating the definite integral. Here, you could do this for a traditional, what if It would have actually evaluated the definite integral. Video, you could have also used a typical graphingĬalculator to come up with the same result, and Orange, the area, I guess the overlap between these twoĬircles and we came up with nine pi minus 18 all of that over eight. ![]() Guess this combined area between the blue and this Video, we tried to find the area of the region, I ![]()
