HELP ASAP!!! PLEASE WRITE A PARAGRAPH ON THIS. DOESN'T HAVE TO BE LONG I JUST NEED SOMETHING! What is the relation between the sine and cosine values of angles in each quadrant?

The Answer to Your Question :

Sin(x) and Cos(x) are each other’s derivative functions.

dSin(x)/dx = Cos(x)

dCos(x)/dx = -Sin(x)

Here are some other relationships where x is between 0 and 90

Sin(90 - x) = Cos(x)

Cos(90 - x) = Sin(x)

Sin(90 + x) = Cos(x)

Cos(90 + x) = -Sin(x)

Sin(270 - x) = -Sin(x)

Cos(270 - x) = Cos(x)

Sin(270 + x) = -Cos(x)

Cos(270 + x) = Sin(x)

Some multiple angle sin-cos relationships

sin(x/2) = +-sqrt((1-cos(x))/2)

Some helpful facts

Sin(-x) = -Sin(x) [due to perfect asymmetry about x=0]

Cos(-x) = Cos(x) [due to symmetry about x=0]

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
