After short consideration, we see that we must integrate f(x) with respect to x, between 0 and π/2, using integration by parts. Taking the formula for integration by parts, we set u = x and dv/dx = sin(2x...
Take, for example, the bracket (a+5)^2. The longer way to do it would be to write (a+5)^2 as (a+5)(a+5) and multiply out that way. However, there is a shorter way where all you have to do is square the fi...
Integration is the reverse of calculating the derivative in maths. We can use integration to determine the area under a graph between to x values. I will demonstrate a basic integration question to show y...
When considering a term in the form of xn, we use the rule nxn-1 when differentiating.
So, we multiply the power of x by the coefficient (number in front) of x and then minus ...
Label the two equations.
x2 + 8x + y2 = 84 (1) x - y = 10 (2)
Rearrange (2) to get y = x - 10 and substitute for y in (1) to get x2 + 8x + (x - 10)LTAnswered by Lewis T. • Maths tutor4997 Views
