How could I find x in this equation
Evaluate the following:
is this diagram exponential rational logarithmic polinomica
and are the roots of the quadratic equation.
then quadratic equation, whose roots are and is:
I tried finding the sum and product of roots and placing in the equation but I was not able to solve for it.
Find the solution of cos B csc B tan = 1
Let . Let A be a positive-definite symmetric matrix. Is there a general formula for ?
For example, let
This is equal to where is the Hadamard product of x,y.
It seems that also works for . Is this true in the general case, and if so, how do I prove it? If not, how can I find and prove a general formula?
