Thanks ..domt forger to rate 5 stars to the course
sir pls add materices and determinants
ur videos are too awesome
sir cos(-theta) is cos (theta) ...sir apko kaise pta ki so 4th qudrant me jayega...I mean theta ka Value to kitna v ho skta hai hai na..negative direction me kisi v qudrant me ja skta hai

sin(90-Q) =cos Q likhte ho na ? ..kya pta Q 90 se Bda ho and 90-Q negative ban ke 4th quad mein aa jaye ?? aise toh koi bhi identity ap likh he ni paoge because u dont know the angle
is possible to can be write as cos 870

dont see like tht....frst apply the formula of cos (-theta) and then lower the angle ...when angle comes less than 360 then see the quadrant
