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) - 1
Substitute 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 verify cos2 theta divided by csc2 theta plus cos4 theta equals cos2 theta?
Using x instead of theta, cos2x/cosec2x + cos4x = cos2x*sin2x + cos4x = cos2x*(sin2x + cos2x) = cos2x*1 = cos2x
Can sine theta equals tan theta equals theta be equal for small angels?
Yes. (Theta in radians, and then approximately, not exactly.)
How do you figure this out Sin theta equals 0.0138 so theta equals what?
theta = arcsin(0.0138) is the principal value.
Sec squared theta plus tan squared theta equals to 13 12 and sec raised to 4 theta minus tan raised to 4 theta equals to how much?
It also equals 13 12.
What is cosine 2 theta when sine theta equals .28?
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432

How can you verify 1 plus tan theta divided by 1 minus tan theta equals cot theta plus 1 divided by cot theta minus 1?
It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.

theta = arcsin(0.0138) is the principal value.
Tan theta plus cot theta equals 2csc2 theta?
Yes, it is.
Sec squared theta plus tan squared theta equals to 13 12 and sec raised to 4 theta minus tan raised to 4 theta equals to how much?
It also equals 13 12.
Sin theta equals zero answer in radians in terms of pi?
Theta equals 0 or pi.
What is cosine 2 theta when sine theta equals .28?
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
Should we find cos theta if sec theta equals -10?
No.
What quadrant is theta equals 2 in?
The answer depends on what theta is and the units of its measurement.
If tan Theta equals 2 with Theta in Quadrant 3 find cot Theta?
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
How do you solve r squared equals theta?
If r-squared = theta then r = ±sqrt(theta)
