Sign of sin cos tan in quadrants
WebIn the second quadrant, only sine and cosecant (the reciprocal of sine) are positive. In the third quadrant, only tangent and cotangent are positive. Finally, in the fourth quadrant, only cosine and secant are positive. The following diagram may help clarify.

Did you know?
WebWhen you compare the sine leg over the cosine leg of the first triangle with the similar sides of the other triangle, you will find that is equal to the tangent leg over the angle leg. Therefore, SIN/COS = TAN/1 . You can also see that 1/COS = … Web4) If the tangent of an angle is negative and its secant is positive, in which quadrant does the angle terminate? 5) Name the quadrant in which angle 𝜃 may lie if sin 𝜃 > 0 and tan 𝜃 < 0. 6) If cos ? = − √2 2, in which quadrants could ∠? terminate? 7) If sin ? = cos ?, in which quadrant(s) may angle x lie?
WebTrigonometric Values in Different Quadrants. There are six different types of trigonometric functions. These are sine, cosine, tangent, cot, sec, and cosec. Each of them have different values in the quadrant. In the first quadrant and the second quadrant, the sine function has positive values in the graph. WebIn this video, we will learn how to identify which quadrant an angle lies and whether its sine, cosine, and tangent will be positive or negative. First, let’s consider a coordinate grid with an 𝑥- and 𝑦-axis. The top-right quadrant is labeled quadrant one. The top-left quadrant is quadrant …
