Sir, I am a class 11 student. And in our coaching, Trigonometry is going on and they give us DPPs to complete. But I was independently going on with S L Loney''s Plane Trigonometry and since I had a doubt, I asked my Sir about it and he instead advised me not to follow these books as they are outdated currently. He told me to concentrate only on his DPPs. Is it true sir that S L Loney is outdated?
