Common mistakes made when solving Trigonometry problems

Though the students enjoy solving Trigonometry problems, however in many cases they tend to make mistakes. These mistakes could be because of carelessness or because the child did not understand the concept properly. It is always a good idea to be aware about the common mistakes which students usually make so that these can be corrected from the early age. Here are some of the common mistakes which students usually make when solving Trigonometry problems.

☞ cotθ=tan-1θ

The correct answer is cotθ=1/tanθ

Ways to teach the children to minimize this error
  • cotθ
    However, tan²θ=(tanθ)²
  • ☞ 1+sin²θ=cos²θ

    The correct answer is sin²θ+cos²θ=1

    The best way to remove the above confusion and to ensure the children have less chance of committing mistakes is to practice the problems related to the above situations. Click on Trigonometry to practice.
