Answer:

2 is the evaluated value.

Step-by-step explanation:

We have:

⇒ tan 45° + cos 0°

We know:

⇒ tan 45° = 1

⇒ cos 0° = 1

Hence:

⇒ tan 45° + cos 0°

⇒ 1 + 1

⇒ 2

Learn more:

⇒ sin 0° = 0

⇒ sin 30° = 1/2

⇒ sin 45° = 1/√2

⇒ sin 60° = √3/2

⇒ sin 90° = 1

=> cos Ф is the reverse of sin Ф

⇒ cos 0° = 1

⇒ cos 30° = √3/2

⇒ cos 45° = 1/√2

⇒ cos 60° = 1/2

⇒ cos 90° = 0

=> tan Ф = sin Ф/cos Ф

⇒ tan 0° = sin 0°/cos 0°

⇒ tan 0° = 1/0

⇒ tan 0 ° = 1

⇒ tan 30° = sin 30°/cos 30°

⇒ tan 30° = (1/2)/(√3/2)

⇒ tan 30° = 1/√3

⇒ tan 45° = sin 45°/cos°

⇒ tan 45° = (1/√2)/(1/√2)

⇒ tan 45° = 1

⇒ tan 60° = sin 60°/cos 60°

⇒ tan 60° = (√3/2)/((1/2)

⇒ tan 60° = √3

⇒ tan 90° = sin 90°/cos 90°

⇒ tan 90° = 1/0

⇒ tan 90° = undefined

Others:

=> tan Ф = 1/cot Ф

=> sin Ф = 1/cosec Ф

=> sec Ф = 1/cos Ф

Step-by-step explanation:

 \tan(45)  +  \cos(0)

1. Get the value of \tan(45) from trigonometric values table.

1 +  \cos(0)

2. Get the value of \cos(0) from trigonometric values table.

1 + 1

3. Add 1 and 1 to get 2.

answer = 2
