ICSE Class 9 Maths Trigonometry

• (tan 60 + 1 / tan 60 - 1 )^2 = 1 + cos 30 / 1 - cos 30
• tan60/sin60+cos30
• sin 47
• Tan2 30°+tan2 45°+tan2 60°
• If 2sin (A+B)-1=0 and 2sin (A-B)-3=0 Find A and B
• HOW TO SOLVE THIS PROBLEM TAN (A+B-C) = 1 SIN (B + C - A ) = 1 COT ( C + A - B ) = 1 FIND A , B and C
