Answer:
Step-by-step explanation:
Sin32° = Sin (90° - 58°) = Cos58° (∵ Sin (90 - θ) = Cosθ)
Tan26° = Tan (90° - 64°) = Cot64° (∵ Tan(90 - θ) = Cotθ)
Cos12° = Cos(90° - 78°) = Sin78° (∵Cos(90 - θ) = Sinθ)
Now substitute the values in the question
Sin32°Sec58° + Tan26°Tan64° + Cos12° - Sin78°
= Cos58° * Sec58° + Cot64° * Tan64° + Sin78° - Sin78°
= 1 + 1 + 0
= 2.
