    How to use SOHCAHTOA to find the missing angle in a right angle triangle
    This video is typically a grade B GCSE question and deals with SOHCAHTOA trigonometry.
    The question asks you to calculate the value of an angle when given the hypoteneuse and adjacent.

Some videos are too fast and are fine for A-A* students or they are aimed at Foundation. You address the middle people who are getting there. I have done a fast pace, year long, adult course to get my skills polished so I can tutor. I am an ex primary teacher. Many thanks...last paper tomorrow. Have a good summer break.

    can you use any of the three different things the same way?... the SOH, CAH, TOA so for instance if i only had the opposite length and the hypotenuse length would i use "SOH" in the same way as "CAH" (Using the sin and sin-1 button on my calculator..)

    • @3minutemaths
      @3minutemaths  Před 9 lety +1

      Hi Ben Target the easiest way is to label your triangle with the opp, adj and hyp. The hyp will always be the same - as its the longest side. The opp will change as you need to label the side opposite to the angle you're working on.
      Hope this is OK and all best
