Which of the following are not trigonometric identities, check all that apply a.) sec^(2) x - tan^(2) x=1 b) sec^(2) x+csc^(2) x=1 c) sin^(2) x + cos^(2) x=1 d) tan^(2) x + sec^(2) x =1

By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are

sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1

So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .

So the correct options are

b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1

Sin^2x-cos^2x=1 & sec^2x-csc^2x=1

Step-by-step explanation:

For those who have a different answer choices that’s the answer.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
