Question

sin∅-cos∅=0prove sec∅=root2

Answer 1

Answer:

1 1 ------- + ------- = 2csc²∅ 1+cos∅ 1-cos Please help me, i cant understand it. ... sin csc cot tan sec cos of radians to numbers(ie cos (pi/4) == root2 over 2) ... + sin (z) = 0. Prove that cos(2x) + cos(2y) + cos(2z) = sin(2x) + sin(2y) + sin(2z) = 0.

Answer 2

Step-by-step explanation:

▪️FORMULAE:

▪️tan ∅ = sin ∅ / cos ∅

▪️1 = tan 45°

▪️sec 45° = √2

▪️PROOF:

▪️sin ∅ - cos ∅ = 0

▪️sin ∅ = cos ∅

▪️tan ∅ = 1

▪️1 = tan 45°

▪️∅ = 45°

▪️sec ∅ => sec 45° = √2

▪️HENCE PROVED

▪️SOME MORE FORMUALE REALTED 

▪️sec ∅ = tan ∅ × cosec ∅

▪️sec ∅ = 1 / cos ∅

▪️sec ∅ = cosec(90° - ∅)

Hopes it help you❤️❤️
