Solve each equation for o is less than and/or equal to theta is less than and/or equal to 360--sin^2x = 1 = cos^2x--Work:cos^2x - cos^2x = 00 = 0--Textbook Answers:90 and 270--Btw, how would you isolate for cos^2x = 0? Would it be...x = cos^-1 square root of _____ ?
Solve each equation for 0 is less than and equal to "x" is less than and equal to 3603sinx = 2cos^{2}x-----I don't know how to solve this equation...this is what I have, but I don't know if I'm on the right track or not3sinx = 1 - 2sin^{2}x3sinx - 1 + 2sin^{2}x = 02sin^{2}x + 3si...
Graph this:y greater than or equal to 2x-32x-2y is less than or equal to 12x-2y is less than or equal to 12x is less than or equal 2yx is less than or equal yhow do u graph this? how to graph x is less than or equal to y?
Prove:cos4x = 8cos^4x - 8cos^2x + 1My Attempt:RS:= 4cos^2x (2cos^2x - 1) + 1= 4 cos^2x (cos2x) + 1LS:= cos2(2x)= 2cos^2(2x) - 1= (cos^2(2)) - cos^2(2x)) - 1-----Prove:8cos^4x = cos4x + 4cos2x + 3My Attempt:RS:= cos2(2x) + 4cos(2x) + 3= 2cos^2(2x) - 1 + 2(4)cos^2(2x) - 1 + 3
Solve each equation on the interval:0 is less than and equal to theta is less than and equal to 360--2sin2x = 1-----My Answers:Let y represent 2x2siny = 12siny/2 = 1/2siny = 1/2y = sin^-1(1/2)y = 302x = 302x/2 = 30/2x = 15 (Quadrant 1)Quadrant 2180 - theta= 180 - 30= 1502x = 1502...
Find the value of x in the interval 0 is less than or equal to x and 360 is greater than or equal to x which satisfies the equation cos x - 2 cos x sin x.
If a+b is less than c+d, and d+e is less than a+b than e is (1)less than c (3)less than d(2)equal to c (4)greater than d
what would be the anser to this question: find x is greater than or equal to zero and y is greater than or equal to zero such that x + y is less than or equal to 10 and 5x +2y is greater than or equal to 20 and 2y is greater than or equal to x and x + 3y is minimized.Thanks!
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...
The only ideas that can be used include: area ABCI-RA2(A+B+C-lpi), the Pythagorean theorem: Cos c cos a cos b. Vectors-dot product cross product, sin A-sin a/sin c; cos A-cos a sin b/sin c; spherical law of sines, spherical law of cosines for sides and spherical law of cosin...
