The sides of a parallelogram measure $10$ cm and $18$ cm. One angle of the parallelogram measures $46$ degrees. What is the area of the parallelogram, to ...
I am beginning to learn Calculus 1, and I was taught about the squeeze (sandwich) theorem. It seems to me that all the problems given have $\sin$ involved...
I'm stuck trying to show $E(XY) = E(X)E(Y)$ for $X, Y$ nonnegative bounded independent random variables on a probability space. The definition of ind...
The problem is as follows: A 13-foot ladder leans against the side of a building, forming an angle θ with the ground. Given that the foot of the ladder is...
I've tried to solve this problem, but I am having some problems. I need to find the $y$- intercept of the tangent to $y = \frac{18}{x^2+2}$ at point ...
so I'm confused as to when you actually use continuity correction. If a problem deals with a binomial distribution and we are asked to find probabili...
In my algebra class we are being taught that there are only the 3 basic trig functions (cosine, sine, and tangent). But my friend who is 2 math grade leve...
It is a bit easier to understand the homology $H_1(X, \mathbb Z)$ for various compact surfaces in analogy with handles and so on. There seems to be a nice...
How can we prove that the product of $n$ consecutive integers is divisible by $n$ factorial? Note: In this subsequent question and the comments here the O...
