Question

if sin theta =cos theta find value of2 tan theta+cos theta​

Answer 1

Answer:

Step-by-step explanation:

Given,

sinQ = cosQ

sinQ = sin(90-Q)

[sin and cos are complimentary to each other]

Q=90-Q

2Q=90

Q=45

2tan45 + cos45

2*1 + 1/✓2

2+1/✓2

(2✓2+1)/✓2

Rationalise this now,

✓2*(2✓2+1)/(✓2*✓2)

(4+✓2)/2
