Question

If sin Ɵ - cos Ɵ = 0 then value of sin4 Ɵ + cos4 Ɵ ( sin power4 Ɵ + cos power4 Ɵ) =


1
1 / 2 ( 1 upon 2 )
3 / 4 ( 3 upon 4 )
2

​

Answer 1

Answer:

sinø= cos ø

sin⁴ø+cos⁴ø=cos⁴ø+cos4ø. ...... (1)

= 2cos⁴ø

= cos⁴ø=1/2

by putting the value of cos⁴ø in eq.1

then we get 2

So , sin ⁴ø+cos ⁴ø=2
