If angle A = -31 pi/18 in radians, what is the degree measure of A? If angle A = (-31pi)/(18) in radians, what is the degree measure of A? What is the sine of an acute angle whose cosine is 7/25? What is the cotangent of 720 degrees?
(°). an important geometrical tool that helps to measure the angles in degree is a “protractor”. a protractor has two sets of numbers going in opposite directions. one set goes from 0 to 180 degree on the outer rim and the other set goes from 180 to 0 degree on the inner rim...
Trigonometry The basic trigonometry is used to get the ratio of the sides of a right-angle triangle, depending on the particular need in the problem. The angle between the two sides is determined by relating the trigonometry function with the ratio of the sides. ...
In trigonometry, either of the non-90-degree angles in a right triangle can be defined by ratios called the sine, cosine and tangent. Applying the concept of reciprocal identities, mathematicians define three more ratios. Their names are cosecant, secant and cotangent. Cosecant is the ...

c. Take care using your calculator: The most common problems when using caculator in trigonometry include: Being in the wrong mode (e.g. being in degree mode when you should be in radian mode) Trusting the calculator more than your brain. The calculator will not always give you the correct...
