Find if tan and sin is negative

WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. … Webtan (θ) = −1 tan ( θ) = - 1. Take the inverse tangent of both sides of the equation to extract θ θ from inside the tangent. θ = arctan(−1) θ = arctan ( - 1) Simplify the right side. Tap for more steps... θ = − π 4 θ = - π 4. The tangent function is negative in the second and fourth quadrants. To find the second solution ...

WebYes. If you look at the sine, cosine and tangent graphs, you'll see that they go on forever. The sine and cosine oscillate between -1 and 1 and the tangent function has a range of -infinity to infinity, and repeats every 180°. WebThe tangent ratio is y/x, so the tangent will be negative when x and y have opposite signs. This occurs in the second quadrant (where x is negative but y is positive) and in the fourth quadrant (where x is positive but y is negative). So the sign on the tangent tells me that the end of the angle is in QII or in QIV.
