Question

1)log4 sin п/42)log10 сos п/33)log8 sin 3п/44)log2 cos п/35)og3 1-log4 tg п/4 * log5 cos0

Answer 1

1)log4 sin п/4=-1/4
2)log10 сos п/3=-log10_2
3)log8 sin 3п/4=-1/6
4)log2 cos п/3=-1
5)og3 1-log4 tg п/4 * log5 cos0=0

Answer 2

1) log4 + sin(π/4) Using the identity sin(π/4) = 1/√2, we get: log4 + 1/√2

2) log10 + cos(π/3) Using the identity cos(π/3) = 1/2, we get: log10 + 1/2

3) log8 + sin(3π/4) Using the identity sin(3π/4) = -1/√2, we get: log8 - 1/√2

4) log2 + cos(π/3) Using the identity cos(π/3) = 1/2, we get: log2 + 1/2

5) log3 + 1 - log4 + tan(π/4) * log5 + cos(0) Using the identity tan(π/4) = 1 and cos(0) = 1, we get: log3 + 1 - log4 + 1 * log5 + 1 Simplifying, we get: log3 - log4 + log5 + 2
