YES!!!! Sin(2x) = Sin(x+x') Sin(x+x') = SinxCosx' + CosxSinx' I have put a 'dash' on an 'x' only to show its position in the identity. Both x & x' carry the same value. Hence SinxCosx' + CosxSinx' = Sinx Cos x + Sinx'Cosx => 2SinxCosx
Without an "equals" sign somewhere, no question has been asked,so there's nothing there that needs an answer.Is it the sum that you're looking for ?csc(x) + cot(x) = 1/sin(x) + cos(x)/sin(x) = [1 + cos(x)] / sin(x)
sin2x / (1-cos x) = (1-cos2x) / (1-cos x) = (1-cos x)(1+cos x) / (1-cos x) = (1+cos x) sin2x=1-cos2x as sin2x+cos2x=1 1-cos2x = (1-cos x)(1+cos x) as a2-b2=(a-b)(a+b)
2 cos * cos * -1 = 2cos(square) * -1 =cos(square) + cos(square) *-1 =1- sin(square) +cos(square) * -1 1 - 1 * -1 =0
x = (y-b)/m
y-b/x=m
the answer is: (y-b)/x = m y = mx + b y - b = mx (y-b)/x = m
Not quite. 'm' is the slope of the line. 'b' is the y-intercept The x-intercept is ( -b/m ).
If y = mx + b, then x = (y-b)/m (for m not equal to zero).
The x-intercept is equal to -b/m.
x=b-a
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
7.5
x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0
Y=mx+b. first you subtract b from both sides of the equation. Y-b=mx then you divide m from both sides because x is being multiplied by m. so then you get (y-b)/m=x and that's your answer
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
