This is the same as secant squared theta [sec²(Θ)].
- Take the identity sin²(Θ) + cos²(Θ) = 1
- Divide both sides by cos²(Θ):
- sin²(Θ) / cos²(Θ) = tan²(Θ)
- cos²(Θ) / cos²(Θ) = 1
- 1 / cos²(Θ) = sec²(Θ)
tan²(Θ) + 1 = sec²(Θ)

How do you solve 1- 2cos squared theta without a calculator?
-1
How do you solve 1 minus 2cos squared theta?
Since there is no equation, there is nothing that can be solved.
How do you solve cos theta subtract cos squared theta divide 1 plus cos theta?
The question contains an expression but not an equation. An expression cannot be solved.
What is sine squared theta subtract six cosine squared theta divided by one minus seven cosine squared theta?
It is 1.
How do you prove cot squared theta plus cos squared theta plus sin squared theta scs squared theta?
Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.
How do you solve 1- 2cos squared theta without a calculator?
-1
How do you solve r squared equals theta?
If r-squared = theta then r = ±sqrt(theta)
If cos and theta 0.65 what is the value of sin and theta?
You can use the Pythagorean identity to solve this:(sin theta) squared + (cos theta) squared = 1.
What does negative sine squared plus cosine squared equal?
To determine what negative sine squared plus cosine squared is equal to, start with the primary trigonometric identity, which is based on the pythagorean theorem...sin2(theta) + cos2(theta) = 1... and then solve for the question...cos2(theta) = 1 - sin2(theta)2 cos2(theta) = 1 - sin2(theta) + cos2(theta)2 cos2(theta) - 1 = - sin2(theta) + cos2(theta)
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
How do you solve 1 minus 2cos squared theta?
Since there is no equation, there is nothing that can be solved.
How do you solve cos theta subtract cos squared theta divide 1 plus cos theta?
The question contains an expression but not an equation. An expression cannot be solved.
What is sec squared theta times cos squared theta minus tan squared theta?
Tan^2
How do you solve theta if cos squared theta equals 1 and 0 is less than or equal to theta which is less than 2pi?
cos2(theta) = 1 so cos(theta) = ±1 cos(theta) = -1 => theta = pi cos(theta) = 1 => theta = 0
Is sin squared theta and sin theta squared the same?
Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.
How would you solve and show work for cos2 theta if cos squared theta equals 1 and theta is in the 4th quadrant?
cos2(theta) = 1 cos2(theta) + sin2(theta) = 1 so sin2(theta) = 0 cos(2*theta) = cos2(theta) - sin2(theta) = 1 - 0 = 1
How do you solve tan squared theta - tan theta equals 0?
Let x = theta, since it's easier to type, and is essentially the same variable. Since tan^2(x)=tan(x), you know that tan(x) must either be 1 or zero for this statement to be true. So let tan(x)=0, and solve on your calculator by taking the inverse. Similarly for, tan(x)=1
