Genral solution of:2tan x + 3=0Solve for x if:2tan x +3 =0 and x E[-180;180]
find all solutions in the interval [0,2 pi) sin(x+(3.14/3) + sin(x- 3.14/3) =1 sin^4 x cos^2 xSince sin (a+b) = sina cosb + cosb sina and sin (a-b) = sina cosb - cosb sina, the first problem can be written 2 sin x cos (pi/3)= sin x The solution to sin x = 1 is x = pi/2 For your o...
Prove: 2tan x / 1+ tan^2 x = sin 2 x all work must be shown!
State domain, range, period, vertical asymptotes, zeros, symmetry and y-intercept of y = -2tan(3x + 180°) + 3I just need to know if there is a formula to find the vertical asymptotes, symmetry, and zeros or do I have to solve it graphically.Thanks.
State domain, range, period, vertical asymptotes, zeros, symmetry and y-intercept of y = -2tan(3x + 180) + 3
Factor and simplify using fundamental identities: tan^4x+2tan^2x+1
2) Use the sum and difference identites sin[x + pi/4] + sin[x-pi/4] = -1 sinx cospi/4 + cosxsin pi/4 + sinx cos pi/4 - cosx sin pi/4 = -1 2 sin x cos pi/4 =-1 cos pi/4 = sqr2/2 2sin^x(sqrt2/2) = -1 sin x = -sqrt2 x = 7pi/4 and 5pi/4 Am I correct?
prove these identiessin^2+tan^2=sec^2-cos^2 sin^2 sec^2 +sin^2=tan^2+sin^2
Helle, i need help for simplify the expression: [( cos x) ( sin x) - ( sin x) ( - sin x)] / ( sin x) ²
the original problem was: (sin x + cos x)^2 + (sin x - cos x)^2 = 2steps too pleaseI got 1 for (sin x + cos x)^2 but then what does (sin x - cos x)^2 become since it's minus?
