cos(2x) = cos 2 (x) - sin 2 (x) = 2 cos 2 (x) - 1 = 1 - 2 sin 2 (x). tan(2x) = 2 tan(x) / (1 Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Formulas expressing trigonometric functions of an angle 2x in terms of functions of an angle x, sin(2x) = 2sinxcosx (1) cos(2x) = cos^2x-sin^2x (2) = 2cos^2x-1 (3) = 1-2sin^2x (4) tan(2x) = (2tanx)/(1-tan^2x). If sin(2x) = 0, then 2x = n*pi for some integer n, and on that interval, that gives the values x = 0, pi/2 Expand sin(2x)^2. Apply the sine double-angle identity.

For math, science, nutrition, history Se hela listan på matteboken.se När du skriver 2x= sin⁻¹(0,5) har du alltså missat dels 2x=150grader, dels alla lösningar som ligger N varv bort. Du använder de lösningarna senare (nästan) men talar aldrig om varifrån de kommer. Dessutom missar du att det är 2x som kan vara N varv från 30 grader eller från 150 grader. Alltså är x N halva varv från 15 eller 75 It is indeed true that sin 2 (x) = 1 − cos 2 (x) and that sin 2 (x) = 2 1 − c o s (2 x) .
