Newtons and meters are sometimes related to each other and you can see the relationships within equations. One such equation is that work is equal to the dot product of force and distance. Force has …

We looked at functions and inverses of function. One quick way to see whether something is a function is to do the vertical line test. If a vertical line can ever pass through two points, it's not a …

We mostly looked at problems with sigma notation. At the bottom of the capital (Greek) letter Sigma, there is a variable with the starting point and at the top a finishing point if it is finite or …

There’s a way to check that. Or any similar problem with a square root. Take what you think is the answer, 1 and square it. If you get -1, then yes, it is. If not, it isn’t. 1(1) = 1 Not -1, so no …

We started by looking at the cosine functions of sums and differences. Then used the Pythagorean Theorem on some triangles for some problems using the equations. Fractional exponents like 1/2 and …
