Question

Evaluate each of the following:
tan45°/cosec30°+sec60°/cot45°-5sin90°/2cos0°

Answer 1

Step-by-step explanation:

The answer is 990 but it may be wrong

Answer 2

tan45°/cosec30° +sec60°/cot45° -5sin90°/2cos0° = 0

Step-by-step explanation:

Evaluate tan45°/cosec30° +sec60°/cot45° -5sin90°/2cos0°

Cosec 30°= Sec 60°= 2  

sin 90° = Cos 0°= 1

Cot 45° = tan 45° = 1

 So tan45°/cosec30° +sec60°/cot45° -5sin90°/2cos0°

  = 1/2 + 2/1 - 5(1)/2(1)

  = 1/2 + 2 - 5/2

  = 1 + 4 - 5 / 2

  = 0

Value of tan45°/cosec30° +sec60°/cot45° -5sin90°/2cos0° = 0
