Question

which of the following statement is true? (a) sinq = cos(90 - q) cb (b) cos =tan (90-q) (c) sinq = tan (90 - q) (d) tanq - tan (90-q)
​

Answer 1

Answer:

a)sinq=cos(90-q)

because

cos(90-q)

here 90 multiple by 1 which a odd number

so cos change to sin and it is in 1st quardent so in 1 quardent all( sin/cos/tan/cot/cosrc/sec) positive so cos(90-q) become sin q,,

which is true

Answer 2

Answer:

a) sinq = cos
