Can someone verify that sec4 theta-sec2 theta equals tan4 theta plus tan2 theta?

sec4(Θ) - sec2(Θ) = tan4(Θ) + tan2(Θ)Factor each side: sec2(Θ) [sec2(Θ) - 1] = tan2(Θ) [tan2(Θ) + 1]Use the identitiy: 1 + tan2(Θ) = sec2(Θ)We can also write it as: tan2(Θ) = sec2(Θ) - 1Substitute the first form of the identity in the right side: sec2(Θ) [sec2(Θ) - 1] = tan2(Θ) sec2(Θ)Substitute the second form of the identity in the left side: sec2(Θ) tan2(Θ) = tan2(Θ) sec2(Θ)Is that close enough for you ?Is it worth a trust point ?

How do you convert meter per second squared to km per hour squared?

1 kilometer = 1,000 meters 1 hour = 3,600 seconds 1 meter/sec2 = (1 meter/sec2) x (1 kilometer/1,000 meters) x (3,6002 sec2/hr2) = 12,960 km/hr2 1 km/hr2 = 7.716 x 10-5 meter/sec2

Simplify Secant squared of x minus one?

There is a trigonometric identity that states that sec2(x) - tan2(x) = 1, for every x. By rearranging this formula we can find that sec2(x) - 1 = tan2(x).


What is the formula for calculating the force in newtons when a mass of 5 kg is accelerated at a rate of 2 m/sec2?

The formula for calculating force (F) in newtons is F mass (m) x acceleration (a). In this case, with a mass of 5 kg and acceleration of 2 m/sec2, the force can be calculated as F 5 kg x 2 m/sec2 10 newtons.


How do you graph a tangent function y equals 2tan 2x?

The derivative of a function is the function's tangent function.So, d(y)/dx = d(2tan(2x))/dx = 2*d(tan(2x))/dx = 2*d(tan(u))/du*du/dx, where u=2x, = 2*sec2(2x)*d(2x)/dx = 4*sec2(2x)*d(x)/dx = 4*sec2(2x)Now just make a plot for y = 4*sec2(2x) and you got your tangent function.
