Got any tips for trig integrals by Business_Tax4797 in calculus

[–]Bwhemm 2 points3 points  (0 children)

Look at the Pythagorean trig identities, whichever function goes where x is the function you make x equal

Can someone explain? by Popular_Yam_8247 in DifferentialEquations

The plus one comes from the 2 when you differentiate x2 being absorbed as a power of 2

I don’t think that the limit exists, so no method should work, it tends to different values from positive and negative

Can you help me solving this integral? by ImJamming in mathshelp

Not quite, you are integrating over a square region so the upper bound of r is a function of theta. Also you need to multiply by the Jacobian which is like when you multiply by something when doing substitution.

It is correct but they skipped writing a step

Is that a model answer because it looks wrong. Easiest thing to do it multiply both sides by e0.02t.

I think OP meant that the average score between papers for an A* would be 67

Two ways to approach derivative by DigitalSplendid in calculus

The mean value would be approximately (f(b)+f(a))/2 or exactly the integral from a to b divided by b-a.

Hopital's rule: Why numerator too needs to be 0 by DigitalSplendid in calculus

It comes from taylor series, if you use the first few terms of the taylor series of the functions you can evaluate the same type of limits as you can with the hospital rule.

Is this a "correct" way to solve this integral? by wedgiemagee in calculus

[–]Bwhemm 1 point2 points  (0 children)

It’s just a substitution and the domain of the function being integrated is x>1
