336 soln i think.
convert cos 3x to sin(90-3x)
and sinC-sinD will help i.e convert it to products.......
:P but i don't remeber the formula.....:P so u better try this way...
33Actually it is asked for no of solns only so rough sketch will help...
(I solved this by roughs sketch lets see if 6 soln is correct :).
1thanks abhishek..
wonderful graph ipower..
how did u make that! i will die in paint :L
16 is right
u can also plot the graph of both func and find the pts of intersections
for such ques where u dont have to give the values this method do the magic in less than 1s !!!!!!!!!!!!!
sorry!!! i am being too unrealistic
30s is fine
33Is that prog which sketches curve for any fnctns.......
These are helpful but U should use it wisely it can block ur thinking process...
1swetha!!!!! how on earth u thought that he sketched that on paint
my god
it is like unifying all the laws of physics in a single equation.
1you are right about saying not using it. but it is not for drawing graphs actually. it is for euclidean geometry.
1:P
:P

ok i only meant about all grpahs.. i find it tough to make any diagram in general
:P
:P

In the above question,how can we convert sin2x into cos(90-2x)??what if 2x were greater than 90deg???Please reply!!
Well Krish.. this formula works for all x.. there is nothing special about x being less than 90
sin(x)=cos(90-x) for all x! :)
