Using trigonometric identities (video)

There are three Pythagorean trigonometric identities in trigonometry that are based on the right-triangle theorem or Pythagoras theorem. sin2 a + cos2 a = 1 1+tan2 a = sec2 a cosec2 a = 1 +

7.1 Solving Trigonometric Equations with Identities

Again, the answer is no. We must pick one side to work on ( HINT: pick the side that looks “nasty” and complicated because it give you more to work with ), and use our knowledge of our fundamental identities to transform it to look like the other. Do we have to write down theorems

I have used this app many time to proof my work. App is good, but they automatically subscribed, it always helps with my math homework, thank you again, math app. 10/10 gives correct answers every time, it's a life saver this app is great but I only been using it for a short while and I heard it's broken so it depends what happen in the future.
