Hello guys !! it s deep here
Hey guys, yesterday we learnt the information about sin law and cosine law.here are the some of them formulas that how we can find the sides of traingle and angles of traingle.
to find the sides and the angles here are the some of the formulas
a2 =b2 +c2-2bc cosa
b2=a2 + c2 -2ac cosb
c2=a2+b2 -2ab cos
this is the cosine law
