The integration of sin 4x is equal to the negative of one-fourth of the cosine of the angle 4x plus the constant of integration which is mathematically written as ∫sin 4x dx = (-1/4) cos 4x + C, where C is the constant of integration, dx indicates the integration of sin 4x w.r.t. x and ∫ is the symbol of integration.What is the integration of Cos 3x?
The formula for the integral of cos 3x is ∫cos 3x dx = (1/3) sin 3x + C, where C is the constant of integration.How do you put cos2x in a calculator?
To enter cos2x into your calculator, calculate cos x and square it. For an algebraic solution write y = cos x and then the equation becomes 2 y2 - 3 y - 4 = 0.What is the derivative of sin2x?
The derivative of sin 2x is 2 cos 2x.How do you find Cos 4pi?
The value of cos 4pi is 1. Cos 4pi can also be expressed using the equivalent of the given angle (4pi) in degrees (720°). Since the cosine function is a periodic function, we can represent cos 4pi as, cos 4pi = cos(4pi + n × 2pi), n ∈ Z. ⇒ cos 4pi = cos 6pi = cos 8pi , and so on.How do you solve sin 3pi?
The value of sin 3pi can be calculated by constructing an angle of 3π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of sin 3pi is equal to the y-coordinate (0). ∴ sin 3pi = 0.How do you solve Cos 3pi pi 4?
The value of cos 3pi/4 can be calculated by constructing an angle of 3π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cos 3pi/4 is equal to the x-coordinate (-0.7071). ∴ cos 3pi/4 = -0.7071.What is the formula of sin 3x?
