How to solve $\\tan^2 \\theta − 2 \\sec \\theta = 2$

WebInstead, think that the tangent of an angle in the unit circle is the slope. If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) and y / x for those weird numbers is 1 so tan 45 ...

WebSolve the equation exactly: tan(θ − π 2) = 1, 0 ≤ θ < 2π. Solution Recall that the tangent function has a period of π. On the interval [0, π) ,and at the angle of π 4 ,the tangent has a value of 1. However, the angle we want is (θ − π 2). Thus, if tan(π 4) = 1 ,then θ − π 2 = π 4 θ = 3π 4 ± kπ Over the interval [0, 2π) ,we have two solutions: WebSolve tan(θ)=sqrt(3), θ in [0, 360)Find all the values of θ so that tan(θ)=sqrt(3)how to solve trigonometric equations, how to find all solutions of a trig e... chubby unicorn coloring pages
