We have that
<span>sin (7π/12)=?
we know that
</span>7π/12=(π/4+π/3)
and
<span><span>sin<span>(A+B)</span>=sin<span>(A)</span>cos<span>(B)</span>+cos<span>(A)</span>sin<span>(B)
then
</span></span>sin(π/4+π/3)=sin(π/4)cos(π/3)+cos(π/4)sin(π/3)
sin(π/4+π/3)=(√2/2)(1/2)+(√2/2)(√3/2)-------> (√2/4)+(√6/4)---> (√2+√6)/4
the answer is (√2+√6)/4
</span>
The answer is(4 -3.5x-15)hope this can help
