prove that sinQ-cosQ+1/sinQ+cosQ-1 =1/secQ-tanQ

To prove that sinQ-cosQ+1/sinQ+cosQ-1 =1/secQ-tanQ

Consider LHS

LHS => SinQ-cosQ+1/sinQ+cosQ+1

=>  (sinQ/cosQ-cosQ/cosQ+1/cosQ)/(sinQ/cosQ+cosQ/cosQ-1/cosQ)                   (divide nominator and denominate by cosQ)

=>  (tanQ-1+secQ)/(tanQ+1-secQ)

=> (tanQ+secQ-1)/(tanQ-secQ+1)

=> (tanQ+secQ-1)/(tanQ-secQ+(sec²Q-tan²Q)     (since sec²Q-tan²Q=1)

=> (tanQ+secQ-1)/(tanQ-secQ+[(secQ-tanQ)(secQ+tanQ)]

=> (tanQ+secQ-1)/-(secQ-tanQ)+[(secQ-tanQ)(secQ+tanQ)]


=> 1/secQ-tanQ  (since  (tanQ+secQ-1)/[(secQ+tanQ)-1]=1)

=> RHS

=> Hence Proved

Is south Indian rivers making big sounds in their flows?

South Indian a union of Telugu ,Tamil,Kannada and Malayalam.Even though their language are different they all enjoy idili ,vada and dosa for their breakfast.In north they are identified has one name, Madrassi.since they have lot of relationship between their language , the way they speak their skin color and their food.but most of them out side madras ,don’t like the identification by the name “Madrassi”.

Most of south India population depend upon agriculture ,especially in Tamil Nadu and Karnataka, good percentage of their population depend on water is important for them.Their main water source is river.almost all river are flowing from one state to another state.So here is the issues are coming.


Let we check the important river that make big sounds in their flow

cauvery (Kaveri) : is a large Indian river. The origin of the river is at Talakaveri, Kodagu in Karnataka, flows generally south and east through Karnataka and Tamil Nadu and across the southern Deccan. Nowadays cauvery  making big sounds in south Indian politics.The issue came up with sharing water in between Tamil Nadu and Karnataka.still we  have to find out a good solution for this issue.

Periyar river : is the longest river, here is the issues between Tamil Nadu and Kerala.the main issues is in the name of Mullaperiyar Dam.This issues  also based on sharing water to Tamil Nadu and the strength of the Dam.

Krishna : It flows through Maharashtra, Karnataka and Andhra Pradesh then it flows into the Bay of Bengal.Here the disputes in  between the states of Karnataka, Maharashtra, Telangana and Andhra Pradeshbecause in the name sharing of Krishna river water.

Palar River: is a river of southern India. It rises in Nandi Hills, India in Kolar district of Karnataka state, and flows 93 kilometres in Karnataka, 33 kilometres in Andhra Pradesh and 222 kilometres in Tamil Nadu.Here is issues between Andhra Pradesh and Tamil Nadu in the name of DAM construction near Kuppam.

In the above rivers some are making big sounds in some areas.we have to bring back its regular rhythm flow . we have to bring back that rhythm because we all are Indians. don’t forget the pledge that we took in our school days.

“All Indians are my sisters and brothers”
