Prove identity sin4x equals 4sinxcosx times 1 minus 2sin squared x?
sin4x=(4sinxcosx)(1-2sin^2x)
Solve 3sin x equals 2 for 0x360?
3 sin(x) = 2sin(x) = 2/3x = 41.81 degreesx = 138.19 degrees
2 sin x plus 1 equals 3 cos x - 1?
2sin(x+1)=3cos(x-1)Since there is only one variable in this equation, it cannot be implicitly differentiated.
Which trigonometric factor can be greater than 1?
2sin(x), or 5.4cos(y), tan(z)
Where is the area vector for a sphere?
R^2sin(theta)d(theta)d(phi)(r-hat)
Prove identity sin4x equals 4sinxcosx times 1 minus 2sin squared x?

What is the period of the function y equals 2sin x?
2 pi
1-2sin squared x equals?

Solve 3sin x equals 2 for 0x360?
3 sin(x) = 2sin(x) = 2/3x = 41.81 degreesx = 138.19 degrees
If tan y equals to x where y is acute find 2 sin y in terms of x?
2sin(y) = 2x/sqrt(1+x^2)
Math trig graph y equals -2sin x?
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
Sin2x plus cosx equals 0?
sin 2x + cos x = 0 (substitute 2sin x cos x for sin 2x)2sin x cos x + cos x = 0 (divide by cos x each term to both sides)2sin x + 1 = 0 (subtract 1 to both sides)2sin x = -1 (divide by 2 to both sides)sin x = -1/2Because the period of the sine function is 360⁰, first find all solutions in [0, 360⁰].Because sin 30⁰ = 1/2 , the solutions of sin x = -1/2 in [0, 360] arex = 180⁰ + 30⁰ = 210⁰ (the sine is negative in the third quadrant)x = 360⁰ - 30⁰ = 330⁰ (the sine is negative in the fourth quadrant)Thus, the solutions of the equation are given byx = 210⁰ + 360⁰n and x = 330⁰ + 360⁰n, where n is any integer.
What is the second derivative of y equals 2sinx cosx?
y = 2sin(x)cos(x)Use the product rule: uv' + vu' where u is 2sin(x) and v is cos(x) to find first derivative:y' = 2sin(x)(-sin(x)) + cos(x)2cos(x)Simplify:y' = 2cos2(x)-2sin2(x)y' = 2(cos2(x)-sin2(x))Use trig identity cos(2x) = cos2(x)-sin2(x):y' = 2cos(2x)Take second derivative using chain rule:y'' = 2(-sin(2x)cos(2x))Simplify:y'' = -2sin(2x)(2)Simplify:y'' = -4sin(2x)y'' = -4sin(2x)
2 sin x plus 1 equals 3 cos x - 1?
2sin(x+1)=3cos(x-1)Since there is only one variable in this equation, it cannot be implicitly differentiated.
Y equals 8 plus 2 sin x?

How do you finish the equation sin 2 theta?
(/) = theta sin 2(/) = 2sin(/)cos(/)
What is the range of the function y 2sin x?
The answer will range between '2' & '-2' Reason; The Sine function ranges between '1' & '-1' , so if it has a coefficient of '2', this will increase the range to '2' & '-2'.
