What is the minimum value of cos 2x SEC 2x?

Now cos^2 x+ sec^2 x=1/(1+tan^2 x)+(1+tan^2 x) now when x=0 then the expression becomes 1/(1+0)+(1+0)=1/1+1=1+1=2 which is the minimum value.

What is the minimum value of Secant theta cos squared theta?

2
We know, arithmatic mean of two terms is always greater than or equal to their geometric mean. So, minimum value of cos2θ+sec2θ is 2.

What is minimum value of sec theta?

Answer: At θ = π/2 +ε , sec(θ) = -Infinity; At θ = π , sec(θ) = – 1; At θ = 3π/2 -ε, sec(θ) = -Infinity; Note2: In this interval sec(θ) has a minimum of -Infinity , and a max of -1.

What is the maximum value of Secant Theta?

Maximum value of Sec theta is 1.

Does SEC equal 1 cosine?

tan x = +∞. x = …, − 3π 2 , − π 2 , π 2 , 3π 2 ,… Thus, sec x and tan x have the same domains. The range of sec x is a bit more complicated: remember that the bounds on cosx are −1 ≤ cos x ≤ 1.

What is the minimum value of SEC?

Minimum value of sec a and cosec a is 1. As the minimum value will always be sec 0° or cosec 0° which is 1.

What is the minimum value of cos2x + sec2x?

Simply, taking x= cos^2 x, the minimum value of cos^2x + sec^2x is 2. (a+b)/2 is greater than or equal to sqrt (ab) . 8 clever moves when you have $1,000 in the bank.

What is the value of sin 2 θ + cos2 θ?

We know that sin 2 θ + cos 2 θ = 1 (identitiy#1) (sin2 θ + cos2 θ) + sec 2 θ + cosec 2 θ + tan 2 θ + cot 2 θ = (1) + sec 2 θ + cosec 2 θ + tan 2 θ + cot 2 θ Using A.M ≥ G.M logic for tan 2 θ + cot 2 θ we get , = 1 + 2 + sec 2 θ + cosec 2 θ

How to find min value of sin θ + cosec θ?

Sometimes, we come across a special case of trigonometric identities like to find min. value of sin θ + cosec θ or tan θ + cot θ or cos2 θ + sec2 θ etc. These identities have one thing in common i.e., the first trigonometric term is opposite of the second term or vice-versa ( tan θ = 1/ cot θ , sin θ = 1/ cosec θ , cos2 θ = 1/ sec2 θ ).
