Web1 dag geleden · we can draw the integral of sin (x), ∫f (x) dx = −cos (x) + C (C= constant of integration) and derivative of sin (x),f′ (x) as cos (x). We can determine the values of sine function as positive or negative depending upon the quadrants. Here is a table where we can see that on one hand sine 270 is negative and on the other hand sine 90 is ... WebIn quadrants 1 and 2, the "y" coordinate is positive, so the sine function is positive. In quadrants 3 and 4, the y-coordinate is negative, so the sine function is negative as well. Example 2. State the sign of cos 70 ∘. The angle 70 ∘ is in the first quadrant. Cosine is defined to be the adjacent side divided by the hypotenuse.
