Since 0 is not a solution, divide both sides of the. Doing it with cosine does produce 4 answers: 2sinx = 1 divide by 2.
( cos x 2 − sin x 2) ( 2 sin x 2) = 0. Sin(x) = 0 sin ( x) = 0. X = 2πn,π+ 2πn x = 2 π n, π + 2 π n, for any integer n n.
Subtract 1 1 from both sides of the equation. By inspection, it is obvious, that: Please be sure to answer the question.provide details và share your research!
Take the inverse tangent of both sides of the equation to extract x x from inside the tangent. Math expression renderer, plots, unit converter, equation solver, complex numbers, calculation history. A solution set is a set of points that satisfies a given equation.
Which can then be solved using standard methods. First of all, 0 is not a solution because cos (0) = 1, and sin (0) = 0. The other answers explain how to arrive at a solution using algebra, but here's a conceptual answer that might make it click a little more.
And cosx = 0 at pi/2 and 3pi/2 (restricting ourselves to [0,2pi]) The correct step is as follow cos2x = 2sinxcosx cos2x− 2sinxcosx = 0 cosx(cosx− 2sinx) = 0 and therefore the original equation is equivalent to the following 2 equations. How would you solve e^(cosx+sinx)=0?
