Answer:
sin θ . tan θ
Step-by-step explanation:
Note : -
sec ( - θ ) = sec θ
Formula / Identity : -
sec θ = 1 / cos θ
sec ( - θ ) - cos θ
= [ 1 / cos θ ] - cos θ
{ LCM = cos θ }
= [ 1 / cos θ ] - [ cos²θ / cos θ ]
= [ 1 - cos²θ ] / cos θ
{ 1 - cos²θ = sin²θ }
= sin²θ / cos θ
{ sin²θ = sin θ . sin θ }
= sin θ . sin θ / cos θ
{ sin θ / cos θ = tan θ }
= sin θ . tan θ
Hence, simplified.
Answer:
1
Step-by-step explanation:
i= -1
$11=2 hrs
2hrs=$11
+2(4hrs)=$22
+2(6hrs)=$33 hrs
so 6 hrs or 7 hours and some
minutes left
Answer:
Estimated=189
Exact=190.026
Step-by-step explanation:
Estimated values
20.7 to nearest whole number= 21
9.18 to nearest whole number= 9
Product means multiplication
Estimated product of 20.7 and 9.18
=21×9
=189
Exact product of 20.7 and 9.18
=20.7 × 9.18
=190.026
It has 3 decimal places
