Check the pink box on page 153 in your C2 textbook!

I do Edexcel and that's the first time I hear that o.O

@ iluvme   Hint : in this case you need to use the tabular method and consider the gradient on either side of the stationary point.

How do u solve trig eq. in radians

For example tan(theta + pie/3) =1 in range 0< theta < 2pie

For example tan(theta + pie/3) =1 in range 0< theta < 2pie

Tyvm

Tan(theta+pie/3)=1               

Get the new range, pie/3< theta+pie/3< 2pie+pie/3

Theta +pie = Tan-1(1)

Since tan-1is positive, you get the values in the first and third quadrants.

theta+pie/3= 0.78, (Pie+0.78), (2pie+0.78)

Theta + pie/3 is not equal to 0.78 because of the new range we got, Pie/3<theta +pie/3 < 2pie+pie/3

Therefore,

Theta + pie/3 = 3.93, 7.06

Theta = 2.88, 6.01

Remember to change your calculator mode to Radians
Hope you got it :)

no i mean if r not going to use a calculator so do we have to memorise for example something like squre root of 2 as we would not be able to use calculator for it and also we can not get it by mind like for example square root of 4

For C1 just leave it in the simplified surd form (e.g. Root 2), usually the Q. states that give answer in exact form which means you have to give it in surd form. You definitely don't have to remember the decimal answer.
If for example its Sq. root 12, you can simplify further to give 2sq. root3
