Question

If sin the ta+sin²theta=1,find the value of cos²theta+ cos⁴theta

Answer 1

Answer:

hence the answer is 1.....

Step-by-step explanation:

suppose $ as theta. ok....

sin$ + sin2$ = 1...

sin$ = 1- sin2$

sin$ = cos2$............ . . . identity

now cos2$ + cos 4$

cos2$ + sin$ ka whole square....

cos2$ + sin2$ = 1......
