Trigonometry - Overview and Identities (15 of TBD) sin(2theta) and cos(2theta) Derived
Visit http://ilectureonline.com for more math and science lectures! To donate: http://www.ilectureonline.com/donate https://www.patreon.com/user?u=3236071 We will derive the identities sin[2(theta)]=2[sin(theta)cos(theta)] and cos[2(theta)]=1-2[sin(theta)]^2=2[cos(theta)]^2-1.
