Question

if sin (t)-cos(t)=0 then the value of (t)
​

Answer 1

Answer:

45°

Step-by-step explanation:

sint=cost

45° is the only angle when sint becomes equal to cost

So, the ans is 45°

Answer 2

Given

→ sin (t) - cos (t) = 0

To Find

→ Value of t

Solution

→ sin (t) - cos (t) = 0

→ sin (t) = cos(t) __(1)

Dividing equation (1) by cos (t),

→ sin (t)/cos (t) = cos (t)/cos (t)

→ tan (t) = 1

Since we know that,

• sin∅/cos∅ = tan∅
• and tan 45° = 1

→ tan 45° = 1

→ tan (t) = tan 45°

Hence value of t is 45°.

Answer

→ t = 45°
