XD , WHO IS WRONG????

 

[1357913579]

NO MANNNN FOR CURVE YOU HAD TO WRITE LESS TAHN 30 AND MORE THAN 150

 

[phro5031]

SUM OF POSITIVE TERMS ARE 570 , THE RANGE OF SINX<COS2X IS 0_<X<30 and 150<X_<180

 

[Abdulrab]

were u getting the answer 3under root 3 and 1under root 3 in the ratio question ?? the range was X < 30 and X>150

 

[sarzkhan]

how can the sum be 570 when the total sum was 525.
it was 420

 

[anahita16]

it asked for the sum of the positive terms only, implying there were negative terms involved.
sum of negative terms = -45
total=525
so sum of positive terms= 525-(-45)=525+45=570
