Asap i've been stuck with this for days
use sum and difference identities to verify which of the following are identities.
1) sin(x+ 2pi/4) =√2 sinxcosx
2) cos( x- pi/3) = 3/√2 (cost-sinx)
3) 14( sin^2x - cos^2x - tan^2x) = 14tanxsinx
4) 15( 1-cos^2x / cos^2x) = 15cot^2x
5) 11( csc^2x - sec^2x - cot^2 x)= 11tanxsecx
6) 9( 1-sec^2x/ sec^2x) = 9cot^2x

step-by-step explanation:

0

answer: about 22.67

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
