WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. Websin stands for sine.cos stands for cosine. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine').Co-functions have the relationship sin@ = cos(90-@) However, the trig function csc stands for cosecant which is completely different from cosine.As you might have noticed, cosecant has a 'co' written in front of … formula of upthrustWebJul 19, 2015 · Find 3 trig functions of arc 225 deg Answers: sin = cos = -(sqrt22)/2 , tan = 1 On the trig unit circle, the arc 225 is in Quadrant III. sin 225 = sin (45 + 180) = - sin 45 = -(sqrt2)/2 cos 225 = cos (45 + 180) = - cos 45 = - (sqrt2)/2 tan 225 = sin/cos = 1 diffuse axonal injury prognosis children

"WebExplanation: For cos 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 45° value = 1/√2 or 0.7071067. . . ⇒ cos 45° = cos 405° = cos 765°, and so on. Note: Since, cosine is an even function, the value of cos (-45°) = cos (45°). " - Cosine of 225
