52:30. Sin(4pi-theta)=-Sin(theta) because angle is of x axes so it will be as it is and sin is positive because 4 pi is even integral. The angle is of Fourth Quadrant Cos(3pi/2+ theta) = -Sin(theta) because the angle is of y axes and of Fourth Quadrant so first of all cos will be converted to sin and the sin is negative in fourth quadrant hence answer is -sin(theta)

32:00 ye question to dusre method se bhi bn sakti h na jaise ki x ke place PE koi bhi value daal kr put krenge to perpendicular bada hi aayega aur p/h mein hypotenuse kabhi chota nhi ho sakta. 🙂 Can anyone explain this is right or wrong?

Easy trick to remember sign scheme is to learn ALL , SIN , TAN COS then in 1st quadrant :- All means all value +ve 2nd quadrat:' Only sin and cosec thita give +ve value 3rd quadrant:- Only Tan and cot thita gives +ve value 4th quadrant:- Only Cos and sec thita give +ve values.😁👍

Sin(4pi-thita)=(-sin thita) because it lies in 4th quadrant. Since 4pi lies on x axis positive side.But cos(3pi by thita+thita)=(+sin thita)because it lies in 4 quadrant. So thi is the answer. Is it right? If wrong then reply me .😊

Cos (3pi+theta) = -sintheta Because it is in third quadrant and it is in multiple of odd number due to which cos changes into sin and it contains negative sign because cos is negative in this quadrant

[@thecaptainpaul]

Bro that's right but bro cos 3pie/2+theta is in 4th quadrant and it contains negative sign because cos and sec is only signed with +ve so sin will be -ve there
