First write everything in terms of sines and cosines.
2 sin x / cos x - (1 / cos x)2 = 0
Multiply by the common denominator, cos2x:
2 sin x cos x - 1 = 0
Solve:
2 sin x cos x = 1
sin 2x = 1
2x = pi/2, or 2x = 5pi/2, or 2x = 9pi/2...
For the first one, 2x = pi/2 --> x = pi/4.
It also equals 13 12.
There is nothing to solve in this equation because there is no =. If you accidentally omitted what the expression equals then resubmit it and I'll be happy to look at it
No. It equals 32 feet per second squared, or 32 ft sec-2
Given y = tan x: dy/dx = sec^2 x(secant of x squared)
1/45 sec or 0.023 sec
It also equals 13 12.
Yes.

No. It equals 32 feet per second squared, or 32 ft sec-2
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
Tan^2
Given y = tan x: dy/dx = sec^2 x(secant of x squared)
1/45 sec or 0.023 sec
Cos x = 1 / Sec x so 1 / Cos x = Sec x Then Tan x = Sin x / Cos x = Sin x * (1 / Cos x) = Sin x * Sec x
