Use substitutionlet u = cos(x)du = - sin(x)dxint(tan(x)) dx = int(sinx/cosx) dx = - int(1/u) du = - ln(u) + c= ln(secx) + c

log2(x + 3) + log2(x - 3) = 4log2 [(x + 3)(x - 3)] = 4x^2 - 9 = 16x^2 = 25x = 5

We will use the cross product of these two vectors to help us find the perpendicular vector. The cross product works by finding a vector which has no effect on the position of a point with respect the the...

A gene is a small section of DNA which codes for a single protein. DNA is made up of a linear sequence of nucleic acids, which may be either A, T, C or G. Three nucleic acids make up a code for one amino ...

Y= mx + cFinding m : change in y/ change in x => (8--7)/(3--2) = 3Finding c : input a pair of coordinates => 8 = (3 x 3) + c .... c = -1y = 3x -1
