1.	Vit cos 30Q. 29. Prove that= = sec 60+tan 60V1 -cos 30
Answer» V1+ Cos30/ V1- Cos30 = V1+ Cos30/V1- Cos30 x 1-Cos30/ 1- Cos30=V(1+Cos30)(1- Cos30)/V1- cos30(1 - Cos30)=V(1-Cos30)^2/V1- Cos30( 1- Cos30)=1- Cos30/Sin30^2=1-V3/2//1/4=2-V3/2 x 4/1=2-V3/2 ×4/1=2-V3/2 1-V3/1/2=(V2+(V3)=sec60 + tan60

Answer»

V1+ Cos30/ V1- Cos30 = V1+ Cos30/V1- Cos30 x 1-Cos30/ 1- Cos30=V(1+Cos30)(1- Cos30)/V1- cos30(1 - Cos30)=V(1-Cos30)^2/V1- Cos30( 1- Cos30)=1- Cos30/Sin30^2=1-V3/2//1/4=2-V3/2 x 4/1=2-V3/2 ×4/1=2-V3/2

1-V3/1/2=(V2+(V3)=sec60 + tan60
