The purpose of Washington's Child Outcome Measurement System (COMS) is to assure stakeholders that early intervention makes a difference for infants,

I myself think that the idea of cos 180 is equal to 1 is : cos 180 = cos(180 - 0) cos 180 = -cos 0 "which is cos(180-a) =- cos a" cos 180 =- 1. Cos 180° Value in Radians / Degrees | Cos Values for 180° Use this simple cos calculator to calculate the cos value for 180° in radians / degrees. The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and Find value of Cos(180) - Cosine or Calculate value of Sin, Cos, Tan, Cot, Cosec, Sec, Sinh, Cosh, Tanh, Coth, Cosech, Sech, Asin, Acos, ATan, ACot, ACosec, ASec and The reciprocal of cosine is the secant: sec(x), sometimes written as secant(x), which gives the ratio of the length of the hypotenuse to the length of the side opposite to the angle. The inverse of the cosine is the arccosine function: acos(x) or arccos(x), which takes values between 0 and 180 degrees. It is useful for finding an angle x when Please see below. One of the easiest ways could be to use the formula cos(A-B)=cosAcosB+sinAsinB Hence, cos(180^o-theta)=cos180^ocostheta+sin180^osintheta = (-1)xxcostheta+0xxsintheta = -costheta Now, use opposite angle identity cos(-A) = cos A. Sin 180°= cos 90° Sin 180°= 0 [Since the value of cos 90 degrees is 0] Therefore, the value of sin 180 is 0.
