Question

sinQ + sinQ²=1 prove cosQ + cosQ²= 1​

Answer 1

Answer:

here you go,

Step-by-step explanation:

1 is sin squar theta + cos square theta

use this in bith equations you will get that

sinQ is equal to cos square Q

and also cosQ is equal to sin square Q

equating both

we get cosQ is equal to sinQ

hence put cosQ in eqn 1

hence proved!
