WebWhy is cos negative in 2nd quadrant? In the second quadrant, x is always negative. So cos θ \displaystyle \cos{\theta} cosθ will always be negative there, too. For the tan θ \displaystyle \tan{\theta} tanθ case, y is positive and x is negative, so xy will always be negative. Considering the other quadrants, we see a pattern. WebTrigonometry Find the Exact Value cos(150) Step 1 Apply the reference angleby finding the anglewith equivalenttrig values in the first quadrant.

WebAn angle whose cosine is negative will fall in the 2nd quadrant, where it will have its smallest absolute value. ( Topic 15 .) The cosine of a 2nd quadrant angle θ is the negative of the cosine of its corresponding acute angle, which is its supplement. In other words: The angle whose cosine is − x is the supplement of the angle whose cosine is x. WebIn the second quadrant, the sine of an angle will be positive, whereas the cosine and tangent will be negative. Finally, in the third quadrant, the tangent is positive, whereas the sine and cosine are negative. In this question, we are told that the sec of angle 𝜃 is less than zero. This means it is negative. We know that the sec of angle ...
Webfor angles with their terminal arm in Quadrant IV, since sine is negative and cosine is positive, tangent is negative. You can plot these points on a coordinate plane to show part of the function, the part between 0 and 2 π . For values of θ less than 0 or greater than 2 π you can find the value of θ using the reference angle .
