WebThe signs of the sine and cosine are determined from the x – and y -values in the quadrant of the original angle. An angle’s reference angle is the size angle, t t, formed by the terminal side of the angle t t and the horizontal axis. Reference angles can be used to find the sine and cosine of the original angle. WebThe unit circle identities such as cosecant, secant, cotangent are the respective reciprocal of the sine, cosine, tangent. Further, we can obtain the value of tanθ by dividing sinθ with cosθ, and we can obtain the value of cotθ by dividing cosθ with sinθ. ... The four quadrants are of equal area and they represent one-fourth of the area ... Websin cos and tan are basically just functions that relate an angle with a ratio of two sides in a right triangle. Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. cynthia grant andover ma
