The tangent function is a mathematical function with equation y = tan(x). ... At x = 0, tangent = 0. This is the origin and the center of the graph. As x ... So we get vertical asymptotes at x = π/2 and at x = 3π/2 in the graph of tangent function. Let us plot the x-axis with the angles from 0 to 2π with ... This is the same as x < tan x. (b) Show that x/ sin x is a strictly increasing function on (0, π/2). Solution: If ... TAN to 90 degrees (PI/2 Radians) is 1/0, which is undefined, so you can't graph a result that's not there. You can get as close as you want to 90 degrees, ... ... x for which sin x tan x = 4, 0 ≤ x < 360°. (Total 8 marks). 9. (a) Solve, for 0 ≤ x < 360°, the equation cos (x − 20°) = −0.437, giving your answers to the. Problem: Find the sum of the roots of $\tan^2x-9\tan x+1=0$ that are between $x=0$ and $x=2\pi$ radians.
