We used the pythagorean identities for unit 4 so will formulas like the double angle formula be important in future units in the same way? almarty2 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010723219 2020-12-11 17:53:58 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010723219 I used to think that you could only find the area of if you had the hight and base of the triangle. Now I know you can find the area of a triangle if you have 2 side lengths of a triangle and the angle between them. almarty2 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010738731 2020-12-11 17:57:32 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010738731 I used to think that in order to find a missing side of the triangle I needed to use the Pythagorean Theorem, however, now I think and know that you can solve either a missing side or angle of a triangle by using the law of sines or cosines, depending on what is given to you in a problem. jitafolla1 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010812148 2020-12-11 18:14:16 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010812148 How can we begin to memorize the double angle formulas and where are they derived from? jitafolla1 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010829872 2020-12-11 18:18:20 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010829872 Having learned the Pythagorean Theorem in geometry enabled us to understand that we can use both the Law of Sines and Law of Cosines in order to find the different parts of a triangle. jitafolla1 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010885266 2020-12-11 18:31:16 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1010885266 I used to think if there was an equation that said cos 2x or sin2x that you could just divide by 2 for both sides. Now i know that you should use the double angle formulas to move forward in the problem. almarty2 https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1011324284 2020-12-11 20:31:27 UTC https://padlet.com/almarty2/7aefvj36xk2vp7h1/wish/1011324284
