Which statement(s) are true based on the Pythagorean identities? sine squared (theta) = 1 + cosine squared theta

1 = secant squared theta minus tangent squared theta

cotangent squared theta = cosecant squared theta minus 1

1 minus tangent squared theta = negative secant squared theta

negative cosine squared theta = sine squared theta minus 1

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
