How do you confirm this trig identity?
sin^5 2x = 1/8 sin2x (cos(8x) - 4 cos(4x)+3)
Express cos4x sin3x in a series of sines of multiples of x?
The best way to answer this question is with the angle addition formulas. Sin(a + b) = sin(a)cos(b) + cos(a)sin(b) and cos(a + b) = cos(a)cos(b) - sin(a)sin(b). If you compute this repeatedly until you get sin(3x)cos(4x) = 3sin(x) - 28sin^3(x) + 56sin^5(x) - 32sin^7(x).
How can you solve this equation 3x-4x plus 9xy-12y?
The given equation: =3x-4x plus 9xy-12y =3x-4x+9xy-12y =-x+9xy-12y =-x+3y(3y-4) Answer.
How do you solve y equals -4x plus 3?
You cannot solve one linear equation with two variables.
What is 4x plus 6x plus 6x plus 9?
16x+9 without the rest of the equation, what this equals, I can't solve
How do you Solve -4x plus 5 plus 9x - 2?
There is no equation, only an expression. An expression can be simplified but cannot be solved.
How do you solve 4x plus y7?
If you mean 4x+y = 7 then y = -4x+7 which is a straight line equation whereas -4 is the slope and 7 is the y intercept
What is the value of x in the equation -4x plus 2 26?
If the equation is -4x + 2 = 26, then you can solve like so: -4x + 2 = 26 -4x = 26 - 2 = 24 4x = -24 x = -6 Check: -6 * -4 = 24, 24 + 2 = 26
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
What is 4x² plus 9x-12 plus 5x²?
9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
How would you solve for y in this problem 4x plus y equals 8?
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
How do you solve 9X plus 7 equals 4X - 8?
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
How do you solve 3x plus 2y equals 4 4x plus 3y equals 7?
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
How do you solve this equation 4x-3y9?
Fortunately,you don't have to, because it's not an equation.
