Trigonometric Ratios of Higher Angles | Mathematical tools | Physics for IIT-JEE Main and Advanced
In this video Trigonometric Ratio of higher angles has been discussed in detail and lucid way by ABJ Sir (Amit Bijarnia Sir-IIT-D). The videos are useful for #JEEMain and #JEEAdvanced and cover the topic in full detail.
CAST rule, trigonometric ratios of angle more than 90 degrees, cos 120, sin 120, cos 180, sin180, examples are discussed by Kota famous faculty Amit Bijarnia ABJ sir

Sir what if we have to find the angles like 138 or 153 degree

[@HIGHNOOBER]

35:00 we can also use complementary angles formula.. Sinx°=Cos(90-x°) Sin(-30°)=Cos{90°-(-30°)}=Cos120°.. Now we can solve it normally. I know it's a longer process than the Sir taught us.

[@Robintalkingtoyou]

Plz solve a doubt of me on this topic

[@Robintalkingtoyou]

See in Sin(-30⁰) Sir thaught us to firs devide -30⁰ with 90⁰ then use the formula .. But how the quotient and reminder came 0 and -30

Sir in previous lecture u told a concept according to which u said that if an angle is measured anticlockwise it's + and when it's measured clockwise it's - so l used this concept in the problem solved at 34:25 and made sin(-30) Sin (330) is it correct?
