Give. 1 (0.4). your answer in the form y = ax + b, where a and b are constants to be found. x + cos. 2 x = 1 sec2 x = 1 + tan. 2 x. We will now use these in the solution ... Suppose we wish to solve the equation 2 cos2 x + sin x = 1 for 0 ≤ x ≤ 2π. May 27, 2021 ... For example, cos(π2)=0 and cos(3π2)=0. At these values, the tangent function is undefined, so the graph of y=tanx ... Since F'(0)=1 (that is, the graph of F is tangent to the diagonal at x=0) this fixed point must be neutral. Moreover, graphical analysis suggest that the fixed ... 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, ...
