A: In a right angled triangle, cosine of an angle is ratio of side adjacent to that angle and side…. WebOr it’s a trick question designed to make to say “that’s impossible”. You should ask your teacher for clarification. There's 2 other problems that just defies the sign for each trigonometric functions. a negative tangent on the third quadrant for one problem and a positive cosine on the third quadrant for the other.
WebAdjacent side = OQ = -5/10 = -0.5 (negative side of x axis) Hypotenuse = OR = 1 (take radius to be positive) We then approximate the trigonometric ratios in the second quadrant. It can be confirmed from tables that these are better approximations. We see that the cosine and tangent are negative in second quadrant while the sine is positive. WebTrigonometric functions sine and cosine are both positive in first quadrant but in third quadrant both are negative. Hence in these two quadrants they have same sign. However, in. second quadrant while sine is positive, cosine is negative. . And in fourth quadrant, cosine is positive and sine is negative.
WebFinal answer. Transcribed image text: (4 points) Suppose A is in Quadrant II and B is in Quadrant II. If sin(A)= 6160 and cos(B) = −419, then sin(A+B) = Compute sin(A−B) = Remark: Your answers cannot contain trigonometric functions. … WebWe first describe trigonometric functions in terms of ratios of two sides of a right angle triangle containing the angle θ. θ. With reference to the above triangle, for an acute angle θ θ (that is, 0 ≤ θ< π/2 0 ≤ θ < π / 2 ), the six trigonometric functions can be described as follows: Definition 1.36.
