Question

sin^4 theta+cos^4 theta/1+2 sin^2 theta cos^2 theta =1​

Answer 1

Answer:

formula used

1.sin^2@+cos^2@=1

2.(a+b)^2=a^2+b^2+2ab

Step-by-step explanation:

sin^4@+cos^4@+2sin^2@cos^2@

=(sin^2@+cos^2@)^2

=(1)^2=1

Answer 2

Answer:

Step-by-step explanation:

sin^4@+cos^4@+2sin^2@cos^2@

=(sin^2@+cos^2@)^2

=(1)^2=1
