3tan(k)-1=sec^2(k) () We want to get this in the form of a quadratic equation in a single variable, and in this case the easiest variable is tan(k). To do this we use the trigonometric identity sec^2(...
First of all we need to convert our decimal negative number into binary without taking the sign into account. Then we have to apply some rules to convert positive binary into a negative one. To do so we h...
Cellular Respiration is a three-step process. The Electron Transport Chain (ETC) is the final step of this process, generating majority of the ATP. The first two steps of Glycolysis and Citric Acid Cycle ...
Let the 2x2 matrix= A. Using the characteristic equation for A (det(A-λI)=0), find the determinant of the matrix (2-λ,1) and (3,-λ). This results in the quadratic λ^2-2λ-3 so λ=3,-1. From the definition o...
Use the identity cos^2(x)+sin^2(x)=1, to change the 5sin^(x) into 5-5cos^2(x) and rearrange. Let y=sin(x) and solve the rearranged quadratic (6y^2-3y-3) for y and find the value of x for each solution. y=...
