spiderman:
Hey guys wud b glad if u cud help me with these sums

find the least 2 +ve values of @...

1)sin(2@+60)=0.3584
2)sin(30-@)=0.5
3)cos(3@-120)=0






  
 

master786:
wat are the limits ?

spiderman:
there are no limits
we just need 2 find d 2 least positive values of @

master786:
for the first sum is the answer 49.5 and 160.5 ?
if its right i will post the method .. :P

spiderman:
Yes it is right
pls cud u post the steps

Thanks in advance

cos(3@-120)=0

(3-120)=cos-10

3-120)=360-cos-10

3-120)=360+cos-10

3-120)=720-cos-10

3-120)=720+cos-10

3-120)=1080-cos-10

3-120)=1080+cos-10


Then solve all thes. Each equation mean a new
