TRIGONOMETRY: RIGHT ANGLE TRIANGLES

Right-angled triangles have one internal angle of 900 (a right angle) shown as a red block in diagram. In a triangle, all of the internal angles add up to 1800. The side opposite angle A is called the opposite side, the horizontal side is called the adjacent side and the longest side (corresponding to the radius in the diagram at upper right) is called the hypotenuse. In this calculator you can get the values of the sine of angle A (opposite divided by hypotenuse), the cosine (adjacent divided by hypotenuse) and the tan or tangent (opposite divided by adjacent). The relationship between circles, sines, cosines and tangents can be seen in our sine wave & cosine animation and in our tangent graph animation.
DEGREES TO RADIANS, SINE, COSINE, & TAN CALCULATOR simply enter the desired number of degrees for angle A in the box in the left column and then click the CALCULATE button to display the equivalent in radians and sine, cosine & tan values and the value for angle B: enter value for angle A (maximum of 900) >> equivalent in RADIANS = SINE of angle = COSINE of angle = TAN of angle = OTHER angle (B) =
