The value of sinπ+2Cosπ+3sin3π/2 +4Cos3π/2-5secπ-6cosec3π/2=​

Answer 1

Question:

The value of

$sin \pi+2Cos \pi+3sin \frac{3 \pi} {2}+4Cos \frac{3 \pi} {2} -5sec \pi -6cosec \frac{3 \pi}{2}$

Solution:

$sin \pi+2Cos \pi+3sin \frac{3 \pi} {2}+4Cos \frac{3 \pi} {2} -5sec \pi -6cosec \frac{3 \pi}{2} \\ 0 + 2( - 1) + ( - 3cos0) + 4sin0 - 5( sec \pi) - 6( - sec0) \\ 0 - 2 - 3 + 0 + 5 + 6 \\ = 11 - 5 \\ = 6$
