` ( sin^(6) x + cos ^(6) x)/( sin ^(2) x cos ^(2) x)`

int ( sin^(6) x + cos ^(6) x + 3 sin ^(2) x cos ^(2) x ) dx is equal to

2(sin^(6) x + cos^(6) x ) -3(sin^(4) x + cos^(4) x ) +1=

Find the value of : 2 (sin^(6) x + cos^(6)x) - 3 (sin^(4) x + cos ^(4)x) + 2 .

Prove that sin^(6)x + cos^(6)x = 1 - 3 sin^(2) x cos^(2)x .

Prove that 3 (sin x-cos x) ^ (4) +4 (sin ^ (6) x + cos ^ (6) x) +6 (sin x + cos x) ^ (2) = 13

Ltquad x rarr0 (1-cos ^ (2) (sin x) -cos (sin ^ (2) x) + cos ^ (2) (sin x) cos (sin ^ (2) x)) / (x ^ ( 6)) =

Prove that: 3 (sin x-cos x) ^ (4) +6 (sin x + cos x) ^ (2) +4 (sin ^ (6) x + cos ^ (6) x) -13 = 0

3(sin x- cos x )^(4) + 6(sin x+ cos x )^(2) +4 (sin ^(6) x+ cos ^(6) x)=

3(sin x- cos x )^(4) + 6(sin x+ cos x )^(2) +4 (sin ^(6) x+ cos ^(6) x)=
