If sin θ - cos θ = $\frac{1}{29}$ find the value of sin θ + cos θ.
Answer & explanation
Correct answer: option 1
sinθ - cosθ = \(\frac{1 }{29}\)
Concept used :-
If (a)sinθ - (b)cosθ = c
then (a)sinθ + (b)cosθ = d
Hence, a² + b² = c² + d²
a = 1 , b = 1 & c = \(\frac{1 }{29}\)
1² + 1² = ( \(\frac{1 }{29}\))² + d²
2 = \(\frac{1 }{841}\) + d²
d² = \(\frac{1681 }{841}\)
d = \(\frac{41 }{29}\)
