It is an isosceles triangle. We know this because 40 + 70 = 110. So we take away 110 from 180 (The sum of the three degrees in a triange) to give us the degree of the last angle, which is 70. Since we hav...

When evaluating more complex exponentials it is helpful to break them up into smaller steps. so when we are aproched with (1/3)^-3/2 we should first look at the effect that the negative sighn ha...

Intergration by parts (IBP). - This accours every time you have a mulitplication in an intergral. This quesion wants you to find the area under the graph x²e^x. For any intergration b...

Given that you have a fraction in the question, you are clearly asked to use the quotient rule. In order to do this, you should label the numerator u, and the denominator v, like this: u = 2x v=cos(x). No...

would use paper to show the student the final answer Your answer will be based around the graph of y=sin(x), which has a y maximum of 1 and minimum of -1, and one full cycle is completed by 2 pi....
