If in some integration, I see the derivative of the base sitting there either directly or as a multiple, the integration becomes routine. so intgr x^2(x^3 - 6)^3 = x^2/(4(3x^2))(x^3 - 6)^4 + c = (1/12)(x^3 - 6)^4 + c check it by differentiating, it works.

double integrals
Combine the following two integrals into one by sketching the region, then switching the order of integration. (sketch the region) im gonna use the S for integral sign..lol SS6ycos(x^3-3x)dxdy+SS6ycos(x^3-3x) And the first integration limits for x are between -1 and y, for y ...

integrate -2/xln^4(x)...plz help me..give me an idea on how to start..plz The derivative of the ln(x) function is 1/x and this is multiplying the ln^4(x). You can thus write the integral as: -2 * 1/5 ln^5(x) + constant. is that the answer? wut about the x infront of ln^(x)......

calculus ((()))
The following equation is separable (please check this is the same as your question after adding appropriate parentheses): du/dt = (2t+sec(2t)) / (2u) transpose terms to get: (2u)du = (2t+sec(2t))dt Integrate both sides (do not forget the integration constant) and substitute u...

My first suggestion was to try the method of "integration by parts", but that may not work. I found a recursion formula for the integral in my Table of Integrals, but it ends up requiring the integral of e^-x/x , which is a new fucntion called the exponential ...

maths
well the only thing about maths is that you get stuck on it which is so annoying well the way i know how to do maths is if your mum or dad has got a calculater then sneak into were they keep it an and use it for your homework or you could just get a nerd to do your maths now ...

calculus - INTEGRATION
This question does not require calculus or integration. It does require that you know the acceleration of gravity is 32 ft/s^2. a. Solve for time t: height = 64 + 16 t - (32/2)t^2 = 0 t^2 -t -4 = 0 t = (1/2)[1+ sqrt17] = 2.562 seconds (ignore then negative root, -1.562 s) b. ...

calculus
I cannot find a closed-form solution for the integral in my Tables of Integrals, but the integral can be obtained quite accurately and easily using Simpson's-rule numerical integration. At x values of 0,0.25, 0.5. 0.75 and 1, the values of the function are: 1, 0.995, 0.957...
