If you dont have any experience with the subject, there is not enough information here to teach it to you.For those of you that have studied the material before, this is a condensed formula sheet to help you prepare for exams.
It is also helpful as a handy homework reference. Therefore x cos sqrt(2)2 y sin, or equivalently: (sqrt(2)2, sqrt(2)2) (cos(p4), sin(p4)). Therefore, the distance from p to 2p can also be notated as 0 to -p, depending on which way you travel the circle. A is called the opposite angle of a, and a is the opposite side of A. Your notes or textbook may use x and y or other variables, but the meanings are the same. ![]() ![]() If you pretend the curve where your thumb meets your hand is a right angle, then you have a right triangle. Your thumb is a, your forefinger is b, and the imaginary line (the hypotenuse) is c. Then the angle at the tip of your forefinger is A, the tip of your thumb is B and the right angle is C. If it is easier for you to memorize these too, go ahead, but usually I just solve for them. It is best to memorize as many as you can, but remember that some can be derived from others (if thats easier for you) and many are related. The trig cheat sheet uses Greek letters such as to represent angles. Please note that where marked below, a and b are angles, and p represents pi3.14159.
