Answer:

Step-by-step explanation: the best way to get this answer is by using a scientific calculator fx-991es plus I recommend

Let's go manual for now.

Let's covert pi/4 to angle

1⁰ =π/180

1 radian =180/π

Therefore π/4 × 180/π

∅ =45⁰

Sin-¹(tan 45⁰)

Tan 45⁰= 1

Sin-¹ (1) = 90⁰. Press { sin,-¹ (1) } on your calculator

Sin-¹ (tan pi/4) = 90⁰
