Mistake: Question 64: The numerator was cos5xcos3x+sin3xcos5x but it is meant to say: cos5xcos3x+sin3xsin5x Luckily the video solution is still correct because I read the question as: cos5xcos3x+sin3xsin5x

The numerator is not a compound angle for number 64 , therefore the uproach is wrong though the prove seems so correct which reult the proof to be incorrect. I enjoyed the video . You are the best Kevin of the best 🤝❤️🔥.

Hi Kevin. In question 8 I used the 270 reduction methods on cos290 and sin250. This led me to an answer of Sin(20 - 30) . According to the cos-sine function rules this is correct since it adds up to 90 with ur answer of -cos80. My question is do I reduce my answer to +sin10 or -sin10?
@kevinmathscience
@kevinmathscience 2 жыл бұрын
Hi Chuma, so sin(20 - 30) would become sin(-10) which is then -sin10 eventually after we reduce that further :)
