• question
  
• trigonometry
  
• Proove that (CotA+CosecA-1)/(CotA-CosecA+1) = (1+CosA)/SinA
• maths sums
  
• prove that cos theta by 1-tan theta+sin theta by 1- cot theta equals to sin theta+ cos theta
• Cosec(theta) - cot(theta) = alpha then cosec(theta)+ cot( alpha)=?  
• (1+secA)/secA = sin²A/(1-cosA)
