Hello. I'm having trouble with the 2 last calculus exercises witch I just can't solve. If someone would please tell me how to solve these two:

1) 1-sinx -cosx +sin2x+cos2x=0

2)log(2 below) (4^(x+1)+4) * log(2below) (4^(x)´+1)=log(1/square root of 2 below) (square root of 1/8)

Thanks to everyone who can help me!!!
