Evaluate

Sin 50°/cos40
+
cosec 40/sec50 - 4cos 50 cosec 40
​

Answer 1

Hey mate!!

•sin50/cos 40 +cosec 40/ sec50 -4cos50 cosec 40

=>cos(90-50)/cos 40 +sec(90-40)/sec 50 -4 cos 50 sec( 90- 40)

since cos (90-x) =sinx , sec(90-x)=cosecx

=>cos40/cos40 +sec 50/sec50 -4 cos 50 sec50

=>1+1-4 since cos x sec x=1

=> -2....✌️❤️
