First of all, we have to raise to the power of two the first equation and will obtain: p^2 + 5q = 64. We have to proceed the same for the second equation and will obtain: p^2 - 3q = 36. Second step is to sub...

Your personal statement should spend two thirds discussing why you want to study the degree you are applying for. This includes explaining what you love about the subject and any experience you have in the a...

Step 1: Rearrange y = arctan(x) as tan(y) = x. Step 2: Use implicit differentiation to differentiate this with respect to x, which gives us: (dy/dx)*(sec(y))^2 = 1. Step 3: Rearrange this equation to give us...

Sin^2(x) cannot be integrated in its current form so you must use trigonometric identities to change sin^2(x) into something else. Use the formula for cox(2x): cos(2x)=cos(x+x)=cos^2(x)-sin^2(x) Now use that...

Effective use of graphs is almost guaranteed to bring you extra points in the exam. There are a few things to help you use them well.1) Use relevant graphs. There is no point, for example, drawing a Demand a...
