festival ? what is bro yapping about ?

[@rahimali4191]

which table r u talking abour ..that one jisme tan sin cos tan ki 30 45 60 or 90 ka radian me values thi??

[@saadsohail4690]

yes

[@hassaanamir1042]

I have a question, in second part why didnt you used tan identities instead of cos identities?

[@eihabshakeel4397]

table ki values b toh ham calculator me daal sktay ha

[@unsound2246]

Calculator always rationalizes automatically a value . If u see original value of sin45 or cos45 that is 1/2½ the calculator will give u 2½/2 . So u see that the value differs from its original value. And for tan30 which is 1/3½ the calculator will again give a different value (3½/3)

[@saadsohail4690]

In p1 we are allowed calculator, so why does it matter if we have memorized the table or not.

[@aisha524]

sometimes question asks for exact values, which the calculator does not always give

Plz add lectures on add maths syllabus also

[@ZAINEMATICS]

Please watch all the A levels p1 videos. They are completely in line with add maths syllabus. Only exceptions are differentiation and integration.

[@tanshitsarmadi6591]

@@ZAINEMATICS except for integration and differentiation, are there any differences between any other chapters?

[@randomfellow1483]

is trigonometry Type 3, 4 and 5 in AS syllabus as for the year 2025?

[@Gekohehe]

yes

[@aimenabbasiop]

Can we use pythagoras theorem to get the length of sides?

[@ZAINEMATICS]

where beta

[@aimenabbasiop]

@@ZAINEMATICS In the figure, instead of using cos(theta), can we calculate the length of sides using pythagora’s theorem?

[@Mahmood0419]

@@aimenabbasiopwe cannot do that

[@aimenabbasiop]

@@Mahmood0419 we can do that acc i tried it works

Great :)

[@mmustafaw]

is this for AS?

[@ZAINEMATICS]

yes

[@skphantom8649]

type 3 4 and 5 As me hei plz reply

[@ambermalik9220]

Yes bro in p1
