W.r.t. 56:11 - As far as "Negative Functions" are concerned, sign of a trigonometric functions depends on the quadrant in which the angle i.e. theta falls. Whether theta is a Positive angle or negative angle, if theta falls in a quadrant where a trigonometric function is positive then that trigonometric function (-theta) and trigonometric function (+theta) would be positive only.
Great Lecture maam, Thank you for this. Additionally, At 1:56:50 There's a mistake The cos theorum is cosx= cosy implies x= 2n∏ +_ y but here you added + (-1)^n and removed the -sign later. Posted so that noone makes mistakes 🙌🏻.
@@shalinipawar3893 he meant to say that Y= 2npi + ( -1)^npi/3 that step will not be there while solving cos functions general equation. Ma'am did that wrong
to memorize the table [25:02] just memorize for sin theta for cos it is reverse of sin for tan... divide sin/cos like for 30 degree = 1/2 / root3/2 = 1/ root3 ez :)
co-function is also called as complementary functions ma'am for example cos=complementary of sin (full form of cos) cot=complementary of tan and cosec=complementary of sec
54:52 Mam for us our teacher gave in a different and easy method and I still get the answer 20 i.e One revolution refers to 360 degree which gives the value 0… In the same way we should consider 4 revolutions i.e 360X4 and we’ll get 1440 and here the value will become 0…Now the question is 1410 so we need to add 30 to get the required number…Therefore we’ll get cosec 30 which is equal to 2 !! I hope this is clear!!❤
Fantastic explanation mam ! You have explained all the concepts in so easy way so that anyone can understand them easily ! I was looking for a video on You Tube for my cousin that covers all the topics of class 11th trigonometry and I found this video most useful and now I'm gonna recommend this video to him so that he can also crystal clear his concepts with your most simplified explanation 😊👌👌
