I was given the matrix: $$A=\left(\begin{matrix}-4 & -7 & 1 & 2\\ 0 & 0 & 3 & 8\\5 & -1 &1 & -4\end{matrix}\right)$$ I...

So if I know the angles of a right triangle and I knew the hypotenuse of the triangle, how would I find the length of the other two sides?

The question is : $\dfrac{\csc x}{\sec x} = \cot x$ After solving a bit I get $$\frac{\frac1{\sin x}}{\frac1{\cos x}} = \frac{\cos x}{\sin x}$$ $$\frac{\c...

This might seem like an inappropriate question and even though its easy to retort using analytic geometry, I don't feel convinced that a tangent real...

What's the graph or table of values of $y=\csc(x) + \cot(x)$? I have already solved and graphed the values of $\csc(x)$ and $\cot(x)$.

I have been in conflict with myself because of a confusion about the point convergence of sequences of functions and the uniform convergence over an arbit...

This question is distinct from Exponential growth of cow populations in Minecraft in that an important constraint present in Minecraft is missing from tha...

The Conjugate Roots Theorem for Irrational Roots states that for a polynomial $f(x)$ with integer coefficients, if a root of the equation $f(x) = 0$ is ex...

How do I solve this equation I found in my textbook: $\sqrt{x^2-16} - (x-4) = \sqrt{x^2-5x+4}$ This is what I tried: $\sqrt{x^2-16} - (x-4) = \sqrt{x^2-5x...

I saw an equation as the following one. What is the meaning of the symbol looking like an inverse T? How about the symbol "^"? ///////////////////////////...
