Can tan theta be negative

WebMar 10, 2015 · This means that if you give a number to the arctangent function, most calculators respond with an answer between − 90 ∘ and 90 ∘. This is the half-plane on the right, quadrants I and IV, so x is assumed positive. If x is negative, the answer you want is 180 ∘ away. Share. WebThis is because up until 90 degrees (or pi/2 radians) the circle is in quadrant 1 at the right angle when it reaches the y axis y is still positive, but now x is 0 quadrant 2 has x negative now, since it is on the left of the y axis. if it's easier you can remember x = 1 is on the right of the y axis, and x = -1 is on the left.

WebDec 20, 2024 · We can interpret the tangent of a negative angle as tan( − θ) = sin( − θ) cos( − θ) = − sinθ cosθ = − tanθ. Tangent is therefore an odd function. The cotangent identity, cot( − θ) = − cotθ, also follows from the sine and cosine identities. We can interpret the cotangent of a negative angle as cot( − θ) = cos( − θ) sin( − θ) = cosθ − sinθ = − cotθ. Webθ = − π 3 θ = - π 3.
