Decide whether to integrate with respect to x or y. Integrate both sides with respect to x: dy dx = − Z sinxdx = −(−cosx)+A Integrate again: y = sinx+Ax+B where A,B are the two arbitrary constants of the general solution (the equation is second order). d dx (sin(x + y)) = cos(x + y) × d dx (x + y) = cos(x + y)(1 + dy dx) Thus, we get. The integral is the sine integral function. Intergral: xsec^2(6x) dx I set u=sec^2(6x) and dv=x, but the problems seems to get harder as I go on. At x = 1, x 3 / 3 + x = 4/3 At x = 0, x 3 / 3 + x = 0. The definite integral of the function gives the area while the indefinite integral gives the anti-derivative of the function, i.e. ∫ y dx = [int] (x 2 + 1) dx = x 3 / 3 + x. Example 3.6.

Find the area of the region bounded by the curves y = sin^-1(x/6), y = 0, and x = 6 obtained by integrating with respect to y. Since 1 2 1 2 is constant with respect to y y, move 1 2 1 2 out of the integral. Doing this requires using the angle sum formula for sin, as well as trigonometric limits. Oh, so the indefinite integral of 0 gives you a constant. The right hand side of the equation can be written as follows as per chain rule. Use integration by parts to evaluate the definite integral. Example: x + 1 = sqrt (x+1). This gives 0 y 2 and the radius r= y2. Misc 1 Important . (And the domain of integration A is invariant under this reflection). So I'm still confused with if the left side simplifies to f(x), or f(x) + a constant. I found the intersection points of the line and 8x^2 to be (3/8,9/8) and of the line and 2x^2 to be (1/2,1/2), so the area I am finding is shaped like a pointy comma. Besides the fact that I improperly integrated zero, I don't see any errors on the left side of my evaluations. \square! Please Subscribe here, thank you!!!
